| Ñalculation results of length and shape of 2D nonstationary cavities past a wedge at periodic time dependence are presented. The variable cavity length is found in sequential moments by numerical solving the equation of gas mas balance in the cavity. For each iteration the solution is calculated from a linear set of singular integral equations by the method of discrete singularities. The influence of elasticity of the gas filling the two-dimensional ventilated supercavity is investigated. A comparative analysis of unsteady behavior of plane and axisymmetric supercavities is given. |
