Propeller/stern/boundarylayer interaction on axisymmetric bodies : theory and experiment(
Book
)
2 editions published in 1976 in English and held by 4 WorldCat member libraries worldwide
Measurements of the boundarylayer characteristics and pressure distribution on three axisymmetric bodies with and without a propeller in operation are correlated with analytical techniques for computing (1) the interaction between the hull boundary layer flow and the potential flow and (2) the interaction between the operating propeller and the thick stern boundary layer. The agreement between the measured and computed shear stresses, pressure distributions, and velocity profiles was satisfactory except over the last 5 percent of body length on the two fullest afterbodies. An inviscid propellersternboundarylayer interaaction model was developed and found to give accurate predictions of effective velocity profiles. The experimental results show that the potentialflow propellerhull interaction methods give accurate predictions for thrust deduction and the propellerinduced pressure distribution. The present analytical techniques will be useful for predicting the fullscale effective velocity profile for propeller design when account is taken of the effects of Reynolds number, roughness, and propeller suction in modifying the nominal velocity profiles.

Stern BoundaryLayer Flow on Two ThreeDimensional Bodies Having Elliptical Transverse CrossSections(
Book
)
1 edition published in 1980 in English and held by 2 WorldCat member libraries worldwide
A comprehensive set of experimental pressure, velocity and turbulence data are presented for two simple threedimensional models having 2:1 and 3:1 elliptical transverse cross sections. The Lighthill displacement body concept is used to predict the pressure distributions over the models. The predicted pressure distributions are in good agreement with the measured pressure distributions. Around the corner regions over the major axes of the models the threedimensional boundarylayer equations do not predict well the measured mean velocity distributions. In these regions the boundary layers are much thicker than the cross section dimensions and differences in curvatures between the flow and body surface are very large. However, over large areas of relatively flat body surfaces, the computed and measured mean velocity distributions are in good agreement

Supercavitating propellersdesign theory and experimental evaluation by
Bohyun Yim(
)
1 edition published in 1983 in English and held by 0 WorldCat member libraries worldwide
A liftingsurface theory and numerical procedure for designing supercavitating propellers are presented. Both a subcavitating and a supercavitating propeller are represented by vortex and source distributions. Unlike the subcavitating propeller, however, source strengths for a supercavitating propeller are related to cavity thickness, which is not known without examination, and have to be obtained by solving related integral equations. Numerical computations were also used to design two additional supercavitating propellers which were built and tested. The design predictions are compared to the experimental data, both for blade cavity height and performance characteristics, and good correlation is obtained

Corrosion and biofouling on the nonheatexchanger surfaces of an ocean thermal energy conversion power plant: a survey by David W. Taylor Naval Ship Research and Development Center(
)
1 edition published in 1979 in English and held by 0 WorldCat member libraries worldwide
Of the many foreseeable problems confronting economical ocean thermal energy conversion operation, two major items are the deterioration of the structural and functional components, which prevents efficient operation, and the biofouling of the surfaces, which adds excess weight to the floating ocean platform. The techniques required for effective longterm control of deterioration and corrosion have been investigated actively for many years, and successful solutions for most situations have been developed. For the most part, these solutions can be directly transferred to the ocean thermal energy conversion plant. The majority of problems in these areas are expected to be associated with scaleup and will require some advanced development due to the immensity of the ocean thermal energy conversion platform. Current antifouling control systems are not effective for longterm fouling prevention. Commercially available antifouling coatings are limited to a 3year service life in temperate waters, and even shorter in tropical waters. However, underwater cleaning techniques and some foulingcontrol systems presently being used by conventional power plants may find utility on an ocean thermal energy conversion plant. In addition, some recent major advances in longterm antifouling coatings sponsored by the Navy may be applicable to ocean thermal energy conversion. (Author)

A Ray Theory for Nonlinear Ship Waves and Wave Resistance(
)
1 edition published in 1981 in English and held by 0 WorldCat member libraries worldwide
Analytical and numerical methods for application of ray theory in computing ship waves are investigated. The potentially important role of ray theory in analyses of nonlinear waves and wave resistance is demonstrated. The reflection of ship waves from the hull boundary is analyzed here for the first time. When a wave crest touches the ship surface, the ray exactly follows the ship surface. When the wave crest is nearly perpendicular to the ship surface the ray is reflected many times as it propagates along the ship surface. Many rays of reflected elementary waves intersect each other. The envelope to the first reflected rays forms a line like a shock front which borders the area of large waves or breaking waves near the ship. For the Wigley hull, ray paths, wave phases, and directions of elementary waves are computed by the ray theory and a method of computing wave resistance is developed. The wave phase is compared with that of linear theory as a function of shipbeam length ratio to identify the advancement of the bow wave phase which influences the design of bow bulbs. The wave resistance of the Wigley hull is computed using the amplitude function from Michell's then ship theory and compared with values of Michell's wave resistance. The total wave resistance has the phase of hump and hollow shifted considerably. (Author)

Measurement of the pressure distribution on two model propellers by
Stuart D Jessup(
)
1 edition published in 1982 in English and held by 0 WorldCat member libraries worldwide
Experiments are described in which the pressure distribution on two model controllablepitch propellers was measured. The pressure was measured at 40 locations on the blade surface with the propeller operating in both uniform and inclined flow. The discussion of the experimental technique includes a description of the hardware and data analysis systems. The accuracy of the measured pressures was comparable to the measured calibration accuracy, excluding unexpected loading effects observed on some of the gages. The measured mean pressure distributions produced fair correlation with predictions based on equivalent twodimensional bladesection methods at the design advance coefficient. The measured pressure coefficients at certain blade locations were observed to be dependent upon Reynolds number for a given advance coefficient. Boundarylayer separation is thought to have caused the Reynoldsnumber effect. These viscous effects were greater than previously anticipated

FarField Features of the Kelvin Wake(
)
1 edition published in 1986 in English and held by 0 WorldCat member libraries worldwide
The classical Kelvin wake trailing a ship advancing at constant speed in calm water is studied. In particular, asymptotic expressions for determining the far field wake, at large distances behind the ship, are investigated numerically. This analysis indicates that the divergent waves of a surface ship generally are infinitely steep at the track of the ship, even though their amplitude vanishes there; this result is theoretically possible because the wavelength of the divergent waves vanishes at the track of the ship. Inasmuch as infinitely steep water waves cannot exist in reality, the linear no surface tension analysis presented in this study suggests that no divergent waves can exist within a certain region in the vicinity of the track of the ship, and that the Kelvin wake contains three distinct regions: an inner region where only transverse waves can exist; an outer region where both transverse and divergent waves are present; and an intermediate region at the boundary between the inner and outer regions where short steep divergent waves, as well as transverse waves, can be found. Numerical results for a simple bow form show that the inner region is quite narrow, and that the wavelength of the divergent waves at the boundary of the inner region is of the order of 1 to 20 cm, depending on the speed of the ship. These results to be consistent with the narrow Vwakes observed in some SAR images of ship wakes. The small wavelengths mentioned above indicate that the divergent waves in the vicinity of the track of the ship are likely to be significantly altered by surface tension, which must be included in a more realistic analysis
