Волновая фильтрация пульсаций давления с помощью мелкоячеистых сеток

Abstract

The results of experimental studies are presented of testing the antenna element determining the long-wavelength components of wall pressure fluctuations, the design implementation of which is based on the receiver's location in a cavity under the fine mesh grid. The optimal size of the element is defined, at which the maximum averaging of short wavelengths is realized. A method for determining of its effectiveness is suggested.
