Abstract:
An anisotropic gas–surface interaction model is examined for its possible use as a boundary condition in solving a kinetic equation. The surface aerodynamic coefficients and the temperatures obtained by applying a two-parameter anisotropic reflection model and the Cercignani–Lampis boundary condition for external flow problems with various Knudsen numbers and accommodation coefficients are numerically compared. It is shown that the geometry of the body influences the degree of the difference between the solutions for different models of boundary conditions.
Key words:
kinetic equation, method of discrete velocities, Cercignani–Lampis boundary condition, anisotropic reflection model, gas–surface interaction.
