An Algorithm of the Scheme of the Second Method of Integral Relationships for Calculating Supersonic Flow of Equilibrium and Nonequilibrium Gas Streams past Blunt Bodies

摘要

The calculation method and results of solution of a problem of axisymmetric flow around a blunt body of given shape by a supersonic stream of equilibrium- and nonequilibrium-dissociated gas are given. The complete system of equations consists of differential equations in partial derivatives written in divergent form, ordinary differential equations, and finite relations. An approximation system for any order and an algorithm of the problem for multicomponent nonequilibrium flows are given. An algorithm is also given for equilibrium flows and flows of an ideal gas with constant values of specific heat. The type of algorithm is only a function of the variable for which the approximation is made. The introduction of algorithm permits estimating the rate of practical convergence of the method of integral relations. (Author)
