Elementary stochastic treatment of thermal transpiration in terms of the “dusty-gas” model
Abstract
By working in terms of the “dusty-gas” model, in which a capillary or porous solid is treate formally as a conglomerate of statistically-motionless giant molecules, an elementary stochasti treatment of thermal transpiration is given. Specific attention is drawn to the case of an imperfect gas in the transition region between the Knudsen and continuum limits.
