Fig. 2- Assembly of Pressure Wave Supercharger Fig.1- PWS Element Rotor After applying the boundary conditions for the model or giving all the solutions for the meshed surfaces, the results can be viewed. For boundary conditions, air is selected to enter the inlets. It is assumed that there is no cavitation effect due to the flow of air. Although due to flow of gases at high pressure and temperature, the flow of the gases and air can be considered partially turbulent. The thermal characteristics of the model are selected to get temperature readings at the outlet. The rotor is given an angular speed of 35000 rpm approximately. The mass flow rate at the cold inlet is 5.104kg/s and the mass flow rate at the exhaust inlet is 7.656kg/s. These conditions are then applied and the results are then viewed. There is a separate rotating element in the model, the rotor which needs to be meshed differently. Hence, a meshing of the rotor is done having element size of 0.005 m. Now the extracted volume and the rotor have been meshed and then boundary conditions have to be set for the model. The type of meshing done on the model and the rotor is tetrahedral meshing. This kind of mesh contains 4 vertices, 6 edges, and is bounded by 4 triangular faces. The tetrahedral volume mesh is generated automatically.
