An integrated physical and mathematical model of conjugate heat and mass transfer in super- and hypersonic flows around the blunt anisotropic bodies with determination of their thermal state is proposed. Also proposed is a technique for the numerical solution of the problems for conjugate heat exchange between gas-dynamic near-wall flows and bodies, the thermal conductivity of which is described by the second rank tensor. It is shown that variation of the tensor components of the material external layer thermal conductivity influences significantly the conjugation boundary temperature, which, in its turn, changes the heat flows to the body at the expense of temperature gradient at the conjugation boundary, density and dynamic viscosity. 相似文献

We present a mathematical model, worked out on the basis of the law of binder composite material (CM) decomposition suggested by authors for numerical solution of the heat and mass transfer problems in the heat protective CM under conditions of aero-gas-dynamic heating. The model makes it possible not to consider hard-realizable chemical kinetics of the binder decomposition and can practically be applied to any CM under high temperature conditions. Numerical examples are given. 相似文献
