A flow induced around a sphere with a non-uniform surface temperature in a rarefied gas is investigated using the linearized Boltzmann equation for hard-sphere molecules and the diffuse reflection condition. With the aid of the accurate and efficient numerical method developed by the authors with Aoki, the behaviour of the gas (the velocity distribution function as well as macroscopic variables and force on the sphere) is clarified for the whole range of the Knudsen number. In addition, the solutions of the drag and thermal force (thermophoresis) problems of a spherical particle with an arbitrary thermal conductivity are obtained by appropriate superpositions of the present solution and those of a sphere with infinite thermal conductivity, obtained by the authors with Aoki. The resulting thermal force is compared with various experimental data.
