Numerical study of the flows of a viscous compressible gas and an equilibrium gas mixture in a twodimensional nozzle in the presence of intense blowing
Abstract
Consideration of the problem of the interaction between a viscous supersonic flow in a twodimensional nozzle and a transverse gas stream of the same composition blown through a slit in one of the nozzle walls. The complete NavierStokes equations are used as the initial equations. The conditions at the blowing slit are obtained under the assumption that the blown jet flow up to the blowing slit is described by onedimensional equations of ideal gasdynamics. The proposed model of the interaction is generalized to the case of the flow of a multicomponent gas mixture in chemical equilibrium. Exact solutions obtained previously by the authors (1973) are used as the boundary conditions at the inlet to the investigated section of the nozzle. The results of numerical calculations of the flows of a homogeneous nonreacting gas and an equilibrium gas mixture consisting of four components are presented for various values of the parameters of the main flow and the blown jet.
