Study of temperature field non-uniformity influence on pressure pulsations in inlet duct using RANS/ILES-method

The paper is dedicated to application of high resolution RANS/ILES-method for study of temperature field non-uniformity influence on throttle characteristic, sound pressure level and pressure pulsation spectra of supersonic mixed compression inlet. Five cases of inflow were investigated, three of them were non-uniform. Sound pressure level distribution in the inlet duct and pressure pulsation spectra on inlet walls were obtained.
