摘要

friction dominated, subsonic compressible flow in micro-channels of slowly varying cross-section is treated by developing a perturbation scheme which yields equations of "lubrication" approximation as the first order one. In this context several charac- teristic problems are encountered, such as isothermal flow, non-isothermal flow with prescribed wall temperature, and non-iso- thermal flow with prescribed wall heat flux, which includes the adiabatic wall problem as a special case.
