Abstract:

The two- and three-dimensional hypersonic axisymmetrical flows of a mixture of chemically reacting viscous gases and vapors of a subliming material past blunt body are considered under the effect of a homogeneous magnetic field normal to the body surface. It is assumed that the external electric field is absent, the gas behind the shock wave is sufficiently dense, the applied magnetic field is weak, and the electrical conductivity of both the gas and vapors is constant. Thus, the effect of the induced magnetic field is neglected. The boundary layer equations differ from those of gasdynamics by the term which accounts for a ponderomotive force in the equation of motion. A system of nondimensional equations of a steady self-similar flow regime in the stagnation-point region is derived. The analysis includes the equations of the boundary layer in the gas, and in the molten material, and the equations of thermal conductivity in a solid body with boundary conditions on the outer edge of the boundary layer, on the interface of a gas and a molten material, on the interface of a molten material and a solid body, and inside a solid body. Electrically nonconducting and electrically conducting gas flows were considered. Author
