Several types of flow: problem 1 (sphere cases), problem 2 1-3 (OREX (Orbital Reentry Experiment) cases) and problem 4 1-2 (spherically blunted cone cases) specified in the High Enthalpy Flow Workshop are investigated. Axisymmetric full Navier-Stokes equations which have chemically and thermally nonequilibrium effects are considered by using Park's two-temperature model and the vibrational relaxation model from the SSH (Schwarty-Slawaky-Harzferd) theory. For the time integration, an efficient numerical algorithm of an implicit finite difference method is used, which consists of the combination of LU-SGS (Lower Upper-Symmetric Gauss Seidel) scheme and the implicit diagonal method for a source Jacobian matrix. For convective terms, AUSM (Advection Upstream Splitting Method) DV scheme generalized into the nonequilibrium flow case is applied. Some numerical results of each flow cases are presented and discussed. All cases indicate that the flow inside the shock layer is in strong nonequilibrium and very complex real gas effects are observed. It is shown that fairly reasonable results can be obtained with both numerical methods and physical models applied here. However, numerical results of some cases indicate that more careful analyses and comparison with experimental results are necessary in order to clarify the more complex flow structures in the back flow region.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
