Temperature prediction in stratified water : mathematical model-user's manual (supplement to report 16130DJH01/71) by Patrick J Ryan( Book )

3 editions published in 1971 in English and held by 110 WorldCat member libraries worldwide

Predictions of the complex annual cycle of temperature changes in a lake or reservoir are necessary if proper water quality control is to be achieved. Many lakes and reservoirs exhibit horizontal homogeneity and thus a time-dependent, one-dimensional model describing the temperature variation in the vertical direction is adequate. A discretized mathematical model was developed based on the absorption and transmission of solar radiation, convection due to surface cooling and advection due to inflows and outflows. The model contains provision for simultaneous or intermittent withdrawal from multi-level outlets and time of travel for inflows within the reservoir

Ocean thermal energy conversion plants : experimental and analytical study of mixing and recirculation( Book )

1 edition published in 1977 in English and held by 52 WorldCat member libraries worldwide

Ocean thermal energy conversion (OTEC) is a method of generating power using the vertical temperature gradient of the tropical ocean as an energy source. Experimental and analytical studies have been carried out to determine the characteristics of the temperature and velocity fields induced in the surrounding ocean by the operation of an OTEC plant. The condition of recirculation, i.e. the reentering of mixed discharge water back into the plant intake, was of particular interest because of its adverse effect on plant efficiency. The studies were directed at the mixed discharge concept, in which the evaporator and condenser water flows are exhausted jointly at the approximate level of the ambient ocean thermocline. The OTEC plant was of the symmetric spar-buoy type with radial or separate discharge configurations. A distinctly stratified ocean with uniform, ambient current velocity was assumed. The following conclusions are obtained: The recirculation potential of an OTEC plant in a stagnant ocean is determined by the interaction of the jet discharge zone and a double sink return flow (one sink being the evaporator intake, the other the jet entrainment). This process occurs in the near-field of an OTEC plant up to a distance of about three times the ocean mixed layer depth. The stratified internal flow beyond this zone has little effect on recirculation, as have small ocean current velocities (up to 0.10 m/s prototype). Conditions which are conducive to recirculation are characterized by high discharge velocities and large plant flow rates. A design formula is proposed which determines whether recirculation would occur or not as a function of plant design and ocean conditions. On the basis of these results, it can be concluded that a 100 MW OTEC plant with the mixed discharge mode can operate at a typical candidate ocean site without incurring any discharge recirculation

A mathematical model for the prediction of unsteady salinity intrusion in estuaries by M. Llewellyn Thatcher( Book )

7 editions published between 1922 and 1972 in English and held by 38 WorldCat member libraries worldwide

The salinity structure of a tidal estuary fed by upstream fresh water sources is an important factor of water quality. In addition, this structure is intimately related to the circulation of the estuary because of density currents induced by the salt-fresh water relation. Previous investigations in two and three dimensions have been limited to extremely simplified geometrical and steady-state assumptions. One dimensional studies have considered the variable area case, but have been limited to descriptive rather than predictive methods because of the difficulty of handling the downstream boundary condition for the one-dimensional salt balance equation and because of the necessity to specify a longitudinal dispersion coefficient based on field data for the estuary being studied. This study presents a predictive numerical model of unsteady salinity intrusion in estuaries by formulating the problem in finite-difference terms using the one-dimensional, tidal time, variable area equations for the conservation of water mass, conservation of momentum and conservation of salt. Tidal time means a time scale of calculation larger than that defining turbulence, but much smaller than a tidal period in order to correctly represent the tidal advection within a tidal period. The tidal dynamic equations are coupled to the conservation of salt equation through a salinity-density relationship, and the ocean boundary condition for salt is formulated in a manner which depends on the direction of flow at the entrance to the estuary. The longitudinal dispersion coefficient has been shown to be proportional to the magnitude of the local, time-varying longitudinal salinity gradient, and this constant of proportionality has been shown to depend on a dimensionless parameter which expresses the degree of vertical stratification of the estuary. This relationship has been established for a wide range of stratification conditions. The mathematical model has been verified using data from the Waterways Experiment Station salinity flume and field data from the Delaware, the Potomac, and the Hudson. By specifying initial conditions, fresh water hydrographs, and tidal elevations at the ocean, it is possible to predict the time-varying salinity using this model

Foreword: This report is intended as a documentation of the computer program and as a user's manual for the implementation of the mathematical model for the prediction of unsteady salinity intrusion in estuaries. The details of the model development and verification are contained in the following report: "A Mathematical Model for the Prediction of Unsteady Salinity Intrusion in Estuaries" by M. Llewellyn Thatcher and Donald R.F. Harleman, Ralph M. Parsons Laboratory for Water Resources and Hydrodynamics, Technical Report No. 144, February 1972 also published by M.I.T. Sea Grant Project Office as Report No. MITSG 72-7 (index No. 72-307-Ccb)]. The unsteady salinity intrusion model is one-dimensional, although varying degrees of stratification are accounted for in the assumed longitudinal dispersion relationship. This model is a component in two additional studies, one of which is concerned with the two-dimensional aspects of salinity intrusion (i.e. vertical salinity and velocity distributions in estuaries): "Mathematical Simulation of Tidal Time-Averages of Salinity and Velocity Profiles in Estuaries" by John S. Fisher, John D. Ditmars and Arthur T. Ippen, Ralph M. Parsons Laboratory for Water Resources and Hydrodynamics, Technical Report No. 151, July 1972 [also published by M.I.T. Sea Grant Project Office as Report No. MITSG 72-11 (index No. 72-311-Ccb)] The second study is concerned with the development of a model for predicting the transient longitudinal distribution of water quality parameters in estuaries: "Numerical Model for the Prediction of Transient Water Quality in Estuary Networks" by James E. Dailey and Donald R.F. Harleman, Ralph M. Parsons Laboratory for Water Resources and Hydrodynamics, Technical Report No. 158, October 1972 [also published by M.I.T. Sea Grant Project Office as Report No. MITSG 72-15 (index No. 72-315-Ccb)] This user's manual therefore assists in the implementation of the analytical and numerical models listed above
One-dimensional analysis of salinity intrusion in estuaries by Arthur T Ippen( Book )

7 editions published in 1961 in English and held by 29 WorldCat member libraries worldwide

An experimental and analytical study of the basic factors which determine the instantaneous longitudinal distribution of salinity in a partially mixed estuary of constant section is presented. The mass-transfer equation is solved in two parts: (a) the quasi-steady-state convective-diffusion problem for an observer moving with the tidal velocity, and (b) the cyclic translation of saline water due to the tidal velocity. In the steady-state portion the apparent longitudinal diffusion coefficient is a function of the turbulence induced by the tide and of the internal circulations induced by the density difference. An expression is developed for the intrusion length as a function of the estuary length, mean depth, tidal amplitude and period, fresh-water discharge, ocean salinity, and estuary roughness. A stratification number is defined which expresses the degree of stratification or mixing in an estuary. (Author)

The computation of tides and currents in estuaries and canals by Donald R. F Harleman( Book )

2 editions published in 1969 in English and held by 27 WorldCat member libraries worldwide

The investigation was concerned with analysis of one-dimensional tidal motion in the two principal types of tidal waterways: (1) estuaries open to the ocean at one end and merging with a river at the opposite end; and (2) canals or waterways connecting two independent tidal bodies. The objectives of the research program were to classify tidal problems in terms of boundary conditions, to discuss available analytical and numerical procedures, and to recommend an appropriate method of solution for tidal problems.

An analytical and experimental study of transient cooling pond behavior by P. J Ryan( Book )

4 editions published in 1973 in English and held by 22 WorldCat member libraries worldwide

Cooling ponds offer many advantages as a means of closed cycle heat dissipation. These are simplicity, low maintenance.and power requirements, aesthetic and possible recreational values, and high thermal inertia. A cooling pond is also subject to minimal environmental problems, since fogging tends to be localized, blowdown water can be stored for long periods, and make-up water requirements are intermittent and often lower than for other closed systems. In s~pite of the above advantages it is presently estimated that less than one third of the closed cycle power stations. built in the next 30 years, will utilize cooling ponds. One reason for this is lack of land, but another reason is the lack of confidence in the ability of existing models to predict cooling pond performance under transient heat loads and meteorological conditions. The use of simple steady state models and various commonly used assumptions as to surface heat loss and circulation patterns can lead to differences of at least 100% in the predicted required land area. Physical models have severe limitations, and this uncertainty in design often results in the rejection of the cooling pond alternative, which may be a mistake from economic, aesthetic and environmental considerations. An analytical and experimental investigation of cooling ponds is conducted. The guiding principle of this investigation is that a cooling pond can be designed on a rational basis only if the desired pond behavior is first clearly defined and the important mechanisms of heat transfer both within the pond itself, and at the water surface, are isolated and quantified. An efficient pond has been defined in terms of maximum surface heat transfer and maximum response time; this leads to the requirement that a pond be capable of sustaining a vertical temperature stratification, that entrance mixing be a minimum, and that a skimmer wall intake be used. The various components of heat transfer at a water surface are discussed, and existing empirical formulae are reviewed. Existing formulae for predicting evaporative flux from an artificially heated water surface are found to be unsatisfactory. Field data indicates that commonly used formulae may predict evaporative losses that are too low by as much as 50% for a heavily loaded water surface. A new formulae is proposed which explicitly accounts for mass transfer due to free convection. This can be very significant at low wind speeds. The proposed formula for evaporative flux performs well both in the laboratory and the field. The effect of entrance mixing and density currents on both the steady state and transient behavior of a cooling pond is examined in the laboratory,,and where possible laboratory results are supported by field observations. It is concluded that the reduction of entrance mixing is a very significant factor in improving the pond performance. In a stratified pond density currents can be of paramount importance in distributing the heat to backwater areas, thus making the pond performance essentially independent of shape. Steady state analytical models and a numerical transient model for the prediction of cooling pond performance are developed. The steady state models demonstrate the effect of entrance mixing and different circulation patterns. The major components of the transient model are a relatively thin surface region with horizontal temperature gradients overlying a deeper subsurface region with vertical temperature gradients. The entrance mixing is determined using the Stolzenbach- Harleman surface jet model, and the M.I.T. reservoir model is used to simulate the subsurface behavior. Output is given in terms of transient surface temperature distribution (area under isotherms), transient vertical temperature distribution, and transient intake temperatures. The transient model has been tested in the laboratory, and against five years of field data on two ponds with completely different characteristics, with very satisfactory results. The input data required by the transient model are that which are available before the pond is built, i.e. the model is predictive. The transient mathematical model is relatively simple and inexpensive, with an execution time of less than 1 minute per simulated year on an IBM 370/155. Thus the model can be used as a design tool, or as a component of a management model which compares different heat disposal alternatives. Design considerations, such as design of outlet and intake, the use of internal diking, and the use of physical models are briefly discussed, and a design approach is recommended
