The authors formulate (in the Stokes approximation) a theory of photophoretic, thermophoretic, and diffusophoretic motion of large and moderate-size solid aerosol particles suspended in compressible gaseous media in the case where the particle mean surface temperature is much greater than the temperature of the surrounding medium at infinity. The particle transport process is analyzed at thermal and diffusion Peclet numbers much smaller than unity. The gasdynamic equations are solved with allowance for the compressibility of the gaseous medium along with a power-law temperature dependence for the transfer coefficients. The problem is solved in spherical coordinates with origin at the center of the representative particle.
