Wymiana masy, pędu i energii między cząstką kulistą a otoczeniem gazowym

To the equations of flow of multiphase mixture (see f.e. [25]) enter the relations between thermodynamic forces generating the phase change, and the mass, energy and momentum fluxes. For the mixture near the equilibrium state these relations are linear. Before applying the flow equations to any specific medium, one should know the coefficients in these relations. The coefficients depend on the geometrical structure of the multiphase medium and on the range of Knudsen number. In the paper such coefficients, obtained by different authors for the spherical particle moving with small velocity in the gas medium near the thermodynamic equilibrium, are reviewed in a systematical manner. The results ware obtained on the basis of different models and cover the full range of the Knudsen number.
