Free-molecular gas flow in channels (pores) with physicochemical transformations on the surface
The problems of free-molecular flow of a gas in channels are considered. The literature on the problem is reviewed. The possibility of uniform deposition of a substance on the inside surface of a cylindrical channel is analysed for the case of physicochemical transformations on this surface. The questions of spatial distribution of the molecules outgoing from the channel are discussed. (c) 2005 Elsevier Ltd. All rights reserved.
