The time-dependent Euler solvers provide a single approach for subsonic, transonic and supersonic flows, and have inherent shock capturing capability. So important information of flow field such as shock location and pressure distribution can be provided. Moreover, a very essential part of Navier-Stokes (N-S) solvers are formed, so it is important to develop a robust, accurate, and convergent Euler code. During this development, an insight which is thought to be important is obtained. There exists ambiguity about 'Roe's averaging' on density, and it was found that if this density average is used in inappropriate ways, it is not only analytically incorrect, but can have detrimental effects on numerical simulations. The example for such a case is shown. Also, the result for a transonic compressor rotor cascade at its design point is presented.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
