Motion of heterogeneously burning particles, heated by internal heat sources, in fields of temperature and concentration gradients

This article examines the thermodiffusional and photophoretic motion of heterogeneously burning spherical aerosol particles in three-component gas mixtures in which the distributions of the temperatures and concentrations of the chemically active components are nonuniform. A quasisteady approximation is used to solve a linearized system of Stokes and heat- and mass-transfer equations. Expressions are obtained for the rates of thermophoresis, diffusiophoresis, and photophoresis of the heterogeneously burning particles.
