Modeling of self-oscillations and searching of new self-oscillatory flows

Possible mechanism of self-oscillations in the flows with shocks and contact discontinuities is suggested. Self-oscillatory, according to supposed mechanism, flows in heliosphere and near blunt cones in inhomogeneous stream are considered. Two-dimensional Reynolds equations with turbulent algebraic viscosity are solved by implicit third order Runge–Kutta scheme. The results of numerical investigations are presented.
