Mathematical Models and Computer Simulations Aims and scope

Abstract

The paper is devoted to the RANS/ILES high-resolution method application for studying the influence of a nonuniformity of the inflow temperature field on the throttle characteristics of a supersonic mixed compression inlet, and the intensity and spectral characteristics of pressure pulsations in the inlet duct. Five cases of inflow parameters are investigated, three of which have a nonuniform temperature field. The sound pressure level distributions in the inlet duct and the pressure pulsation spectra at points on the inlet walls are obtained.
