小攻角下轴对称细长体的充气肩空泡试验研究

Water Tunnel Investigation on Ventilated Cavitation for Slender Body at Small Angles of Attack

在减压水洞中进行的空泡试验研究受到各种条件因素的制约，充气空泡的研究是对减压水洞试验的一个很好补充。本文在小型重力式水洞中对轴对称细长体的充气空泡的特征、形态、底压力和水动力等作了尝试性研究。部分结果和自然空泡的测量结果及有关计算结果作了比较，得到了有益的结论。

Experimental study on cavitation in water tunnel is restricted by many factors. As a complement, study on ventilated cavitation is worth considering. In this paper, a water tunnel investigation on ventilated cavitation for slender body at small angles of attack is reported. The shape of cavity, the base pressure and the steady hydrodynamic forces and moments on the slender axisymmetric body are examined in detail in the experiment. Some results are compared with the measurement and calculation for nature cavitation.
