NUMERICAL-SIMULATION OF GAS-FLOW IN PNEUMATIC COMPONENTS

The flow through pneumatic components is characterized by very complex flow phenomina. In general the flow is viscous, transonic (O less-than-or-equal-to M less-than-or-equal-to 4) and turbulent. Small geometrical dimensions of pneumatic components make flow measurement difficult or sometimes impossible. Hence the accurate numerical prediction of the flow field becomes of great importance. In this paper we present the theoretical framework and the numerical capabilities of the commercial Navier-Stokes CFD code TASCflow. We solve some test problems which reflect many features of the numerical flow simulation in pneumatic components. For the test cases considered here, TASCflow was found to be an excellent tool for fast and accurate flow simulation.
