Amplification of Reynolds Number Dependent Processes by Wave Distortion.
Abstract
The object of the research was to investigate the amplification of a Reynolds number dependent process by wave distortion and the possibility of applying the results to other similar Reynolds number dependent processes. The process investigated was that associated with the operation of a constant-temperature hot-wire anemometer. The application of most interest was investigation of vaporization limited combustion, the type combustion typically associated with liquid propellant rocket engines. A series of experiments were carried out to determine the effect of wave distortion on a Reynolds number dependent process and to establish the analogy between the anemometer process and the combustion process. Both analytical and experimental studies were involved, both having the ultimate objective of identifying parametric trends, recognizing behavior common to different chamber geometries and determining stability boundaries. The results indicate a high degree of similarity between the two processes and the possibility of using the anemometer system to investigate combustion instability. The nonlinear aspects of a Reynolds number dependent process appear to be the dominant mechanisms controlling instability. (Author)
