Aeroacoustics : technical papers from AIAA 2nd Aero-acoustics Conference, March 1975, subsequently revised for this volume by AIAA Aero-acoustics Conference ( Book )
7 editions published in 1976 in English and held by 282 WorldCat member libraries worldwide
"The recent progress in duct acoustic research is reflected by fourteen papers which cover essentially the areas of linear duct acoustics, the characteristics of absorbent materials, and nonlinear duct acoustics. With respect to propagation in ducts, emphasis is placed on computational methods aimed at attaining effective economical modeling of propagation in variable-geometry and in hard-wall or soft-wall ducts. Computational methods developed to reduce computer processing and storage requirements are outlined, along with a wave envelope technique for reducing processing and storage needs. The latter technique is applied to the optimum segmented acoustic duct linear design. A finite difference technique is used in combination with conformal mapping to compute the optimum multisection duct linear design."--Publisher description

Combustion noise prediction, entropy/vorticity effects ( Book )
5 editions published in 1979 in English and held by 58 WorldCat member libraries worldwide
An experimental and theoretical program was conducted to see if entropy noise and vorticity-nozzle interaction noise, as well as direct combustion noise, could be isolated in gas turbine combustor tests. Moreover, a unified correlation, with a rational theoretical basis, was developed for direct noise from combustor rig tests. It was found that (a) vorticity noise was at least as large as combustion noise; (b) entropy noise is minor but is large only at low frequency; (c) all noise sources are coherent with each other over various frequency ranges; (d) with a choked nozzle termination the nose is higher frequency (approximately 2000 Hz) than heretofore believed; (e) some other unexplained noise source contaminated the results at low frequency; and (f) the diffuser used caused additional coherent noise, probably through the vorticity source. A method for accounting for the vorticity and entropy sources in combustor rig tests was indicated. (Author)
Aeroacoustics, STOL noise, airframe and airfoil noise : technical papers from AIAA 2nd Aero-acoustics Conference, March 1975, subsequently revised for this volume by AIAA Aero-acoustics Conference ( Book )
2 editions published in 1976 in English and held by 37 WorldCat member libraries worldwide
"The papers in this volume reflect the progress in aeroacoustic research which has been made in the field of VTOL and V/STOL aircraft noise. The research was directed mainly at developing better methods for predicting noise generation and propagation, at determining the effects of pressure fluctuations on surfaces and interior noise, and at developing noise abatement techniques. Among the topics covered are: scrubbing noise of externally blown flaps; propulsive-lift noise of an upper-surface-blown flap configuration; the aeroacoustic characteristics of model slot nozzles with straight flaps; fluctuating pressures on aircraft wing and flap surfaces associated with powered-lift systems; acoustic characteristics of a large upper-surface-blown configuration with turbofan engines; the effect of forward speed on jet/flap interaction noise; and airframe noise in the far field."--Publisher description

The computation of oblique shock wave characteristics for real gases by Warren C Strahle ( Book )
1 edition published in 1961 in English and held by 6 WorldCat member libraries worldwide
A method is presented whereby oblique shock wave data for real gases may be readily obtained from real gas normal shock wave data corresponding to the same upstream thermodynamic state. Although such solutions are well known for perfect gases there appears to be no method available at this time to account for real gas effects. This method is only useful when the flow deflection angle is the specified parameter instead of the wave inclination angle. There is no restriction to any gas com position since the physics of the problem are completely contained in the normal shock characteristics. It is expected that primary use of this method will be found in the study of vehicles for entry into planetary atmospheres. Because of the present uncertainty of the characteristics of any of the planetary atmospheres it is not economically justifiable to compute oblique shock charts for every conceivable model atmosphere. However, to even begin consideration of an entry vehicle requires that some normal shock computations be made. (Author)
Fractal image compression of Rayleigh, Raman, LIF, and LDV data in turbulent reacting flows by Warren C Strahle ( Book )
5 editions published between 1990 and 1991 in English and held by 5 WorldCat member libraries worldwide
Experiments and analysis were completed concerning a diagnostic program on a two dimensional subsonic wind tunnel with a backward facing step and combustion. Combustibles were introduced as a hydrogen-argon mixture from a porous floor behind the step. Completed were LDV and Raman spectroscopy for mean and rms velocity (two components) and temperature. Analysis used a two equation turbulence model which predicted the gross features of the flow but somewhat underpredicted reattachment length. Two dimensional and three dimensional fractal interpolation techniques were developed for reduction of noise to signal ratio in the complex turbulent flow. New methods of fractal analysis of time series were developed
The thermodynamic properties and shock-wave characteristics of a model Venus atmosphere by Warren C Strahle ( Book )
1 edition published in 1962 in English and held by 5 WorldCat member libraries worldwide
A model for the atmosphere of Venus is developed which may be useful for design studies of early atmospheric-entry vehicles and for wind-tunnel simulation application. This atmosphere, derived from many questionable assumptions and scant experimental data, consists of 85% carbon dioxide and 15% nitrogen by volume. The thermodynamic properties of the derived atmospheric composition are presented over the temperaturepressure range of 150 to 24,000 K and 1/10,000 to 100 atm. To further assist in aerodynamic entry calculations, normal-shock-wave characteristics of such an atmosphere are also presented. The fact that nitrogen is present has important consequences in the thermodynamic properties and electron concentrations over the full temperature and pressure range. The effects are of the order of the percentage of nitrogen addition to pure carbon dioxide. A graphical method of obtaining oblique-shock-wave data and a method of obtaining electron concentrations at low temperatures are included as appendixes. (Author)
Audible and Ultrasonic Acoustic Emissions from Composite Solid Propellants ( Book )
4 editions published between 1975 and 1977 in English and held by 4 WorldCat member libraries worldwide
Audible and ultrasonic acoustic waves are generated during deflagration of composite solid propellants. The audible waves can be sensed by microphones while special high frequency pressure transducers are required to measure the ultrasonic signals. These acoustic emissions have a potential use both as diagnostics of the combustion and as a means for the study of fundamental burning processes. To date a family of composite HTPB-AP propellants have been tested. Results which show the effects of pressure level, atmosphere in which burned, AP particle size, aluminum addition, and aluminum coating are presented and discussed. (Author)
Heterogeneous diffusion flame stabilization by Warren C Strahle ( Book )
4 editions published in 1987 in English and held by 4 WorldCat member libraries worldwide
Analytical modelling and several experimental diagnostics were applied to an experimental flow in a two-dimensional subsonic windtunnel with a backward facing step and provision for injection of inerts and combustibles through the porous floor behind the step. The analytical techniques were based on a two equation modeling of turbulence with several variants of near wall models and numerical approaches. Conventional experimental techniques, where applicable in the cold flow, included hot film and pitot and anemometry. Laser - based diagnostics in the cold and hot flows for velocity and species concentration measurements (both mean and instantaneous) included laser velocimetry in two components and Rayleigh molecular scattering. Major findings in this complex turbulent flow with chemical reactions were a) there was a general agreement between analysis and experiment in cold flow both with and without wall injection, b) this agreement occurred at the the most detailed level of turbulent shear stress and mass transport, c) in hot flow there was acceptable agreement as to the gross features of the mean flow field, but some theoretical details, such as reattachment length, went counter to experimental results

Acoustic signature from flames as a combustion diagnostic tool by Warren C Strahle ( Book )
2 editions published in 1983 in English and held by 2 WorldCat member libraries worldwide
A program was conducted to investigate the feasibility of using the combustion noise acoustic output as a non-intrusive diagnostic of some details of the combustion process. Investigated were an open premixed turbulent jet flame and a gas turbine combustor converted to run on propane. The analysis links the acoustic pressure fluctuations to the distribution of heat release rate fluctuations. Measurement of the sound field, yields in principle, the heat release rate fluctuation field. It was found, however, that the analytical methods for this inverse problem are too sensitive to small experimental uncertainties. Consequently, it appears that the method is not, in general feasible
