ABSTRACT

The results of complex experimental and theoretical investigations of features of a transonic flow over a lengthy cavern are presented. The mechanisms of non-stationary processes and some problems of mathematical simulation of a flow in such caverns are considered. Verification of the numerical computations is done using the obtained experimental data.
