| 中文摘要 | 本文对圆形通道内双温度等离子体的传热与流动特性进行了二维数值模拟,研究中假定体系处于局域化学平衡态,但电子温度不等于重粒子温度,需分别用各自的守恒方程求解．采用数值实验的方法对电子-重粒子非弹性碰撞过程进行了研究,计算结果表明,数值模拟中对非弹性碰撞过程不同的处理方法(α的不同取值)会影响计算预测的等离子体特性．α的合适数值,需要在今后的研究工作中进一步将计算结果与实验测量结果比较来加以确定。; In this paper, a two-dimensional simulation is performed about the two-temperature plasma flow and heat transfer in a circular tube. Local chemical equilibrium is assumed for the plasma but its electronic temperature is not equal to the heavy-particle temperature, and the two temperatures are solved using their own governing equations. The electron-heavy particle inelastic collision process is studied through numerical tests. The calculated results show that different treatment of the inelastic collision process (taking different values for the factor a) in numerical simulations will influence the predicted plasma characteristics. In order to determine the appropriate value of a, it is necessary to compare the calculated results with experimental measurements.; 国家自然科学基金资助项目(No．10405015 No．10575127) |
