Abstract

The effect of gravity on the self-similarity of jet shape at late stage of Worthington jet development is investigated by experiment in the study. In addition, the PIV method is introduced to analyze the development of flow field. There is a linear scaling regarding the axial velocity of the jet and the scaling coefficient increases with the Froude number.

重力对二维楔体进水后Worthington射流自相似性的影响

通过实验研究了重力对沃辛顿射流发展后期射流形状自相似性的影响。此外，还引入了PIV方法来分析流场的发展。射流轴向速度随弗劳德数的增加呈线性缩放，且缩放系数随弗劳德数的增加而增大。
