Abstract

The experimental and calculated amplitude-frequency characteristics of pressure pulsations in T-shaped channels are compared. For the numerical simulation, a method was used based on solving the one-dimensional unsteady gas dynamics equations and taking into account the peculiarities in the area of channels branching. A good agreement between the spectra of static pressure pulsations and experimental results is shown.
