Abstract:
In the framework of kinetic approach the
analytic solution (in the form of a series Neumann) of the problem
of isothermal slip gas along a hard, flat surface (Kramers's
problem) is built. The linearized BGK (Bhatnagar, Gross, Krook)
model of Boltzmann's kinetic equation as the main equation and the
model of mirror-diffuse reflection as boundary conditions on the
surface are used. For different values of the coefficient of
diffusely the speed of isothermal slip gas along the surface is
calculated and the profiles of mass velocity are built. The
comparison with similar results, published in the open press is
done.
Keywords:Boltzmann kinetic equation, model kinetic equations, exact
analytical decisions, models of boundary conditions.
