Hydrogen Dissociation in Rarefied Gas Flow Through a Wire Obstacle.

The direct simulation Monte Carlo method was used to study plane-parallel flow of hydrogen through an obstacle formed by a series of parallel infinite wires. Particular attention was paid to the influence of the geometric parameters of the wire obstacle, the degree of rarefaction, and the flow velocity on the degree of hydrogen dissociation due to heterogeneous reactions on the wire surface.
