Supersonic Flow of a Rarefied Gas around a Wire Grid
The direct simulation Monte Carlo method is used to study a plane –parallel supersonic gas flow through a grid formed by a number of infinite parallel wires. Characteristic features of the shock disturbance formation of in the interaction of a supersonic flow with a permeable grid are revealed. Particular attention is paid to studying the influence of geometrical parameters of the wire target on the number of particles colliding with the surface of the wires.
