已知研究认为, 相比冻结流动下的压力值, 热化学非平衡条件下HB2模型扩张裙体部分压力的偏大是由黏性干扰引起的.研究探讨了黏性干扰和高温气体效应对HB2扩张裙体部分压力的影响规律.数值求解了有限速率的N-S方程, 化学反应模型考虑了5种组分、17个基元反应, 并采用Park T-Tv双温度模型求解.对比扩张裙体部分压力对黏性干扰和化学反应的敏感性发现, 热化学反应流动中扩张裙体部分压力的偏大并非由黏性的改变引起, 而是由化学反应所主导.对比流动各参量对压力的贡献值发现, 压力上升速率增加主要来源于温度项的贡献. |

The present work deals with the sensitivity of aerodynamic force to variations in viscous coefficients and chemical reaction rates in thermochemical nonequilibrium flow over HB2 model. Within this scope, numerical simulations are conducted by varying the viscous coefficients and chemical reaction rates over their uncertainty range. The numerical method uses Park's two-temperature model for the description of thermochemical nonequilibrium processes and solves the full N-S equations for a multicomponent reacting gas mixture. The effect of variations in viscous coefficients and chemical reaction rates on pressure coefficient on the flare skirt part shows a big difference. The thicker boundary layer is not the reason for pressure becoming higher on the flare part. It is found that the main contribution to the pressure increase in the nonequilibrium case is the change of temperature due to chemical nonequilibrium, but not the increase of viscous coefficient. |
