Obtained shock stand off distances for seven different cases corresponding to four binary scaling parameters (rho)R, 1.0 x 10(exp -4), 2.0 x 10(exp -4), 4.0 x 10(exp -4), and 1.7 x 10(exp -3) kg/sq m, are compared with the ballistic range data. The governing equations are three dimensional Navier-Stokes equations. Seventeen chemical reactions are considered for five neutral air species, i.e., N2, O2, N, O and NO. Park's reaction rates are employed. The translational-vibrational relaxation rates are given by Landau-Teller equation. Numerical scheme is based on the cell-vertex finite volume method. A prismatic unstructured grid system is employed for avoiding grid singular lines often appearing in structured grid systems, while retaining spatial accuracy in a thin boundary layer. Calculated results show diverse tendency depending on the flight speed and the test section pressure. For lower speed conditions (around 2.6 km/s), the calculated shock stand off distances agree well with the experimental data when the test section pressure is 600-2,400 Pa. On the other hand, when the pressure is increased to 10,130 Pa, the calculation slightly overestimates the stand off distances. For higher speed conditions (around 3.0 km/s), while the agreement can be seen in nearly equilibrium flow condition, the calculations in lower pressure conditions tend to underestimate the shock stand off distances. In order to see effect of thermal relaxation on the shock stand off distances, equilibrium and one temperature calculations are also conducted in the nearly equilibrium flow range where a slight distinction from experiment was observed.","subitem_description_type":"Other"}]},"item_5_description_32":{"attribute_name":"資料番号","attribute_value_mlt":[{"subitem_description":"資料番号:
