In the nature and practical engineering applications, the gas-solid two-phase freeshear flows are typical.
在自然界和实际的工程应用中，气固两相自由剪切流动比较典型。

The dynamics of axisymmetric freeshear flows, axisymmetric variable-density jets and wakes of cylinders have been studied, to a certain extent, under this framework.
基于此种实验研究框架，本文对轴对称自由剪切流、变密度轴对称射流以及圆柱尾迹进行了一定的研究。

So, it is not only of academic theoretical significance but also has the extensive engineering application value to carry out the study on the gas-solid two-phase freeshear flows.
