Abstract:
A numerical method for the Boltzmann kinetic equation is proposed. Elastic
collisions are computed by the projection method. The transfer operator is
approximated using tetrahedral meshes. The main requirements for coordinate
meshes are formulated; it is shown that the usage of variable edge length and
tetrahedron quality optimizers decreases the amount of time needed to solve
the problem. As examples, several models of straight cylindrical and curved
pipes as well as snake Knudsen pumps are discussed.
Keywords:
Boltzmann equation; projection method; tetrahedral meshes; Knudsen pump.
