Abstract : The problem considered is that of rarefied gas flow through a long two-dimenional channel, of length L and width d, connecting two large gas reservoirs at the same tempeature theta, but at slightly different pressures, namely, P1 and P2. The channel walls are also kept at the same temperature theta. Under continuum conditions, the flow rate is known to obey the classical Poiseuille formula. On the other hand, when the mean free path is not very small compared to the width, it is necessary to abandon the continuum approach in favor of the kinetic theory viewpoint. (Author)
