Based on water rotary jet study, the influence rules of macromolecule polymer additives on the configuration character and erosion effect of rotary jet are studied.
在清水旋转射流研究的基础上，研究了高分子聚合物添加剂对旋转射流结构特性及破岩效率的影响规律。
2
The effect made by rotary jetting decreases with the increase ment of Reynolds number.
旋转射流对换热的此种影响随雷诺数的增大而减弱。

And the experiment prove that the sealing effect of flexible rotary seal can be improved by additional reciprocating motion and that the waveform PTFE seal is an optimum flexible rotary seal.
