Abstract:
A rarefied gas flow trough a long circular tube due to pressure and temperature gradients is studied on the basis of the BGK model kinetic equation using a collocation method by the Chebyshev polynomials and rational Chebyshev functions in the whole range of the
Knudsen number covering both free molecular regime and
hydrodynamic one. The mass flux is calculated
as a function of the pressures and temperatures on
the tube ends.
Keywords:
BGK model kinetic equation, model of diffuse reflection, Chebyshev polynomials.
