This paper describes a theoretical study of the steady motion of a large solid nonvolatile aerosol spherical particle, which contains thermal sources within itself, in a concentration gradient of binary gas mixture components. It is assumed that an average particle surface temperature significantly differs from the temperature of the binary gas mixture surrounding it. Equations of gas dynamics are solved taking into account the power-law dependence of the molecular transfer coefficients (viscosity, thermal conductivity, and diffusion) and the density of the gaseous medium on temperature. Under boundary conditions, diffusion and thermal slip are taken into account. Numerical estimates show that the diffusion and photophoretic forces and velocity substantially depend on the average particle surface temperature.

加热的大非挥发性气溶胶球形粒子的扩散和光泳

本文描述了一个大的固体非挥发性气溶胶球形颗粒在二元气体混合物组分的浓度梯度中稳定运动的理论研究，该颗粒本身包含热源。假设平均颗粒表面温度与其周围的二元气体混合物的温度显着不同。考虑到分子传递系数（粘度、热导率和扩散）和气体介质密度对温度的幂律依赖性，求解气体动力学方程。在边界条件下，考虑了扩散和热滑移。数值估计表明，扩散和光泳力和速度基本上取决于平均颗粒表面温度。
