| 摘 要： | 在激波管里进行了可压缩性气固两相流的实验研究。测量了激波通过颗粒群时的压力的衰减过程。用纹影仪拍摄了激波与颗粒群相互干涉的照片。试验了颗粒群的不同构造对压力衰减的影响。指出了激波反射、聚焦等非线性气动因素是可压缩性气固两相流的关键问题。

| Abstract: | The compressible gas-solid two-phase flow is investigated in a shock tube. The shock attenuation caused by solid particles is measured. The shock interaction with the particles is visualized using the schlieren photography. Different structures of particles are tested. It is found that the non-linear aerodynamics is a key factor. |

| Keywords: | gas-solid two-phase flow shock wave pressure visualization non-linear aerodynamics. |
