Effect of Medium Parameters on Pressure Oscillation in Combustion Chamber

Abstract:

To correlate medium parameters and pressure oscillation in SRM (Solid Rocket Motor) combustion chamber, a two-dimensional axisymmetric model was developed based on the typical VKI (Von Karman Institute for Fluid Dynamics) motor. Medium temperature and working pressure as the key parameters, LES (Large Eddy Simulation) was carried out for two groups of different models. Finally, pressure evolution and its FFT (Fast Fourier Transform) results were obtained. It indicates that for SRM with the same structure, medium temperature determines the frequency of pressure oscillation, and working pressure dictates its amplitude.
