低重力環境における熱流体管理に関する研究 : 第1報,熱流動解析に適したCCUP法-TCUP法-の提案(流体工学,流体機械)

抄録

To give appropriate assessment of thermo-fluid phenomena in the space applications under various gravity conditions, the algorithm of CCUP was restructured and expanded for the three-dimensional flows in the curved linear coordinate system. In the modified algorithm, called TCUP, not density but temperature was selected as the independent variable so that the heat transfer even in the incompressible flow field should be simulated adequately. In the present paper, both the supersonic flow field around a right circular cone and the natural convection in a square cavity were simulated with the developed code and the each of numerical results was compared with the theoretical solution or the benchmark result, respectively. Consequently, quite a good agreement was obtained between them.
