The problem of flow of a liquid about a nonuniformly heated droplet at small Reynolds numbers is solved analytically with allowance for the effect of medium motion with arbitrary temperature differences between the particle surface and the region away from it and the temperature dependence of the viscosity, represented in the form of a series. It is shown that in the approximation considered the nonuniformly heated droplet retains a spherical shapeyesBelgorod State Universit

On the influence of motion of the medium on the photophoresis of a spheroidal solid aerosol particle

This paper considers the influence of motion of the medium (account of convective terms in the heat conduction equations) on the photophoresis of a large aerosol spheroidal particle at small relative temperature drops in its vicinity. It has been shown that at a fixed ratio of semiaxes with increasing intensity of the incident radiation the total contribution of the medium motion leads to a monotonic decrease in the rate of photophoresis, whose degree depends on the equatorial radius of the spheroidyesBelgorod State Universit
