Abstract

It is shown that for sufficiently large values of the thermal conductivity of the condensed phaseλ' as compared with the thermal conductivity of the vaporλ (λ/λ' ∼ Kn) the effects associated with the presence of a Knudsen layer on the evaporating surface must be taken into account in order to obtain a solution of the problem of a spherical particle in a slow (Re∞, ≪ 1) continuum (Knudsen number Kn ≪ 1) flow of its own vapor. The drag is calculated for various types of boundary conditions on the particle surface.
