Self-similar turbulent flow of a viscous gas in a wedge

The turbulent steady flow of a viscous gas from a source in a wedge apex is considered. Within the framework of the classical Prandtl mixing length model and the Boussinesque approximation for the tensor of turbulent stress, there is a possibility of self-similar solution. The system of gas dynamic equations is reduced to the system of ordinary differential equations. In the case of arbitrary equations defined parameters, the numerical investigation is carried out and critical values of defining parameters are found. In the case of the flow in a thick wedge, the asymptotic solution is found.
