摘要
对气、固两相正激波松弛流动进行了数值研究。方程中考虑了压力梯度及非匀速运动引起的附加质量力。对不同固相容积比、固相颗粒直径和马赫数进行了广泛的计算。所得计算结果给出了气、固两相的速度、温度、压力、密度、固相容积比及熵值沿流向分布情况。对松弛区中诸参数的变化规律进行了全面的讨论。程序TWSH可完成计算全过程。
A numerical study on gas-solid two-phase relaxation flow with a normal shock wave is here presented. The pressure gradient and the additional body force due to unsteady motion have been considered in the equations. A variety of solid volume ratios, particle diameters and Math numbers are extensively taken in the calculations. The results consist of velocity, temperature pressure, density, volume ratio and entropy variations along the stream direction. A detailed discussion on the regularities concerning two-phase flow parameters in the relaxation region is given in the present paper. Program TWSH can complete the whole calculating procedure.
