物体出水近自由面瞬态流场的试验研究

Experimental Research of Transient Flow Field near Free Surface due to Body Exiting from Water

本文采用PIV测试技术对物体出水近自由面瞬态流场进行了探索试验研究。PIV试验从流场环境定量化分析的角度 ,给出了物体出水近自由面的瞬态历程 ,为全局了解物体出水的复杂流动机理提供了一种细观手段。

The whole history of transient flow field near free surface due to body exiting from water was quantitatively captured by PIV facility .It is shown that PIV system is suitable technical means for strong transient flow problem with free surface.
