    • Kinetic modeling of a tapered Holweck pump 

      Naris, S.; Tantos, C.; Valougeorgis, D. (2014)
      The Holweck pump is a device widely used in many pumping systems. It can be a self-standing device or part of a multi-stage system, usually combined with a turbo-molecular pump (TMP). In the present work, an existing ...

    • Nonlinear vacuum gas flow through a short tube due to pressure and temperature gradients 

      Pantazis, S.; Naris, S.; Tantos, C.; Valougeorgis, D.; Andre, J.; Millet, F.; Perin, J. P. (2013)
      The flow of a rarefied gas through a tube due to both pressure and temperature gradients has been studied numerically. The main objective is to investigate the performance of a mechanical vacuum pump operating at low ...
