Numerical and experimental study of oscillatory processes in small-size combustion heaters of air

摘要

Results of a comprehensive numerical and experimental study of oscillatory processes in combustors of small-size combustion heaters of air are reported. Methods for prediction and experimental determination of regular features of changes in spectral characteristics of pressure oscillations in the combustor in the nominal operation mode are presented. The data obtained in the study can be used for the development of various combustion heaters, including those for testing combustors of air-breathing engines for advanced flying vehicles.
