The equations of motion of a non-stationary radial flow are derived, the boundary value problem is set, and its analytical solution is obtained. The solution of the problem in this paper is in good agreement with the experimental parameters obtained at the experimental setup for small perturbations. The equations for determining the height of the wave front that decreases downstream of the flow are obtained, and the instantaneous velocity of the wave front tends to zero.
