| 摘 要： | 在激波管中用消光法测量了气固两相流动激波松弛区的粒子浓度。基于一维静止激波理论和理想“等效气体”模型,实验确定了粒子阻力系数。拟合实验结果,得到了阻力系数与粒子雷诺数之间的实验关系式:C_D=4300/Re~(1.57)。 |

| Abstract: | The particle concentrations in the relaxation zone behind a shock front for gas-particle mixture flow were measured by extinction method in the vertical shock tube.On the basis of one-dimensional stationary theory and perfect'effective gas" model,the effective drag coefficients are determined experimentally.The obtained correlation of drag coefficient and Reynolds number is Cd=4300/Re1.57 |
| Keywords: | shock tube drag coefficient two-phase flow extinction method. |
