Knudsen flow,divertor exhaust

Gas flow in exhaust path of divertor is in Knudsen's flow region, where conductance of pipes depends on pressure. Then equation describing pressure distribution is nonlinear. We have developed a pressure distribution calculation method based on linearization. Comparing the calculation result to measurement in a small system, validity of the method is confirmed.
