Abstract |
||
The distribution of mass velocity of quantum Bose-gas in half-space is received in the classical problem of physical kinetics - Kramers' problem or the problem of isothermal sliding on a flat firm surface. The mass speed gradient of Bose-gas is set far from the half-space border. The mass velocity of Bose-gas is also found directly at the wall. All the results are received on the basis of the analytical solution of Kramers' problem. The article presents the analysis of velocity coefficients dependence on the parameter value, being the ratio of a chemical potential to the product of Boltzmann constant and the absolute temperature. The article also gives the graphic comparison of the velocity coefficients of Bose- and Fermi-gases. |
