Perfection of nozzle characteristics design techniques based on numerical simulation of resistance and heat exchange in a compressible turbulent boundary layer

The study deals with the design technique of a compressible turbulent boundary layer on a curved surface. The work is aimed at studying heat exchange on curved surfaces under gradient and zero-gradient flows, development on this basis of physically substantiated methods of computation of flows and heat exchange as applied to supersonic nozzles. A mathematical model of a flow and heat exchange in the turbulent boundary layer on curved surfaces under zero-gradient and gradient gas flows has been developed. Laws of resistance and heat exchange have been received as relative functions of curvature and pressure-gradient factor. A program complex has been created based on the numerical solution of the differential equations of the boundary layer. An engineering method of computation of the characteristics of full-scale supersonic nozzles based on the use of relative laws for resistance and heat exchange. The mathematical model for computing energy losses for friction in supersonic turbine nozzles has been implemented at UDN (Moscow) and LSTU (S. Petersburg)Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
