KINETIC THEORY OF RADIOMETRIC PHOTOPHORESIS IN A KNUDSEN GAS,
Abstract
The kinetic theory of a small particle with arbitrary temperature distribution on its surface suspended in a Knudsen gas enclosed by an unequally heated boundary was established according to the revised law of thermal transpiration developed recently by Wu. The external force acting on the particle is mainly due to the radiometric force caused by the incident and the reflecting molecules in the absence of thermal creep effect in this limiting regime. Several particle shapes were considered, such as a small disk, flat plate, sphere and cube presented in a cylinder with uniform temperature gradient in a thermal transpiration system. (Author)
