Thermal Polarization of Bodies in the Rarefied Gas Flow

Diffusiophoresis in Gases

“…(22) are the coefficients of viscous, thermal, and diffusion slip, respectively. These were calculated (Kramers and Kistemaker, 1943;Loyalka, 1971;Bakanov et al, 1981;Zharov, 1972;Lang and Muller, 1975;Markeev, 1976) for a binary gas mixture. The physical sense of the other parameters can be seen from the boundary conditions in Eq.…”

On the Theory of Thermal Polarization of Bodies in a Rarefied Gas Flow

“…Recent experiments [1][2][3] have confirmed the existence of the phenomenon of thermal polarization of bodies in a rarefied gas flow, which had been predicted in [4]. The same experiments have also demonstrated that the measurements of the thermal polarization effect provide an opportunity for determining the values of the momentum and energy accommodation coefficients of gas molecules on the surface of a body.…”

“…The same experiments have also demonstrated that the measurements of the thermal polarization effect provide an opportunity for determining the values of the momentum and energy accommodation coefficients of gas molecules on the surface of a body. At the same time, the accommodation coefficients presented in [1][2][3] are, strictly speaking, unreliable, since in their determination from experimental data the coefficient of the thermal gas slip along a flat surface was used, whereas the accuracy assumed for the Knudsen number which is equal to the ratio of the mean free path of gas molecules to the size of a body, would have required the use of the slip coefficient calculated for a curved surface.…”

A Phenomenological Theory of Particle Motion in Non-Uniform Media

“…This is exemplified in [11][12][13], in which the theory of thermophoresis was tested not on aerosoles but by investigating the effect of thermal polarization of a sphere of -1 cm radius, enveloped by a flow of uniform gas.…”
