dc.description.abstractA novel algorithm recently developed to solve steady-state isothermal vacuum gas dynamics flows through pipe networks consisting of long tubes is extended to include, in addition to long channels, channels of moderate length 10 < LID< 50. This is achieved by implementing the so-called end effect treatment/correction. Analysis and results are based on kinetic theory as described by the Boltzmann equation or associated reliable kinetic model equations. For a pipe network of known geometry the algorithm is capable of computing the mass flow rates (or the conductance) through the pipes as well as the pressure heads at the nodes of the network. The feasibility of the approach is demonstrated by simulating two ITER related vacuum distribution systems, one in the viscous regime and a second one in a wide range of Knudsen numbers. Since a kinetic approach is implemented, the algorithm is valid and the results are accurate in the whole range of the Knudsen number, while the involved computational effort remains small.
