通过一维数值分析，研究了颗粒动量方程中的各种力（阻力、附加质量、Basset历史力和外压梯度力）对激波在气固混合物中传播的影响。在不同的粒子响应时间和初始冲击强度的激波管的低压段的不同位置处的不同的力的时间演化进行了评估。此外，一个有效的阻力系数，其中包括影响颗粒运动的所有力的影响，并与标准阻力曲线和现有的实验数据进行了比较。
The influence of the various forces in the particle momentum equation (i.e. drag force, added mass, Basset history force, and the force due to an external pressure gradient) on the shock wave propagation through a gas-particle mixture were evaluated by one-dimensional numerical analysis. The temporal evolution of the different forces at various locations in the low pressure section of the shock tube were evaluated for different particle response times and initial shock strengths. Furthermore, an effective drag coefficient which includes the influence of all forces affecting the particle motion was determined and compared to the standard drag curve and existing experimental data.
