Flow calculation in the spiral grooves of a vacuum pump in the high pressure regime
碩士 === 國立交通大學 === 機械工程系 === 90 === In this thesis, CFD is used to analyze viscous flow of dynamic meshes in spiral grooved vacuum pumps with ALE method. Unstructured and nonstaggered meshes are adopted in computations. The SIMPLE algorithm is taken to couple velocity-pressure relations and the gover...
