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....

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。

The forming process of natural cavity is closely related to the cavitor, the head shape of which decides the cavity size. Therefore, the study on cavitors has great significance in solving cavitation problem.

The forming process of natural cavity is closely related to the cavitor, the head shape of which decides the cavity size. Therefore, the study on cavitors has great significance in solving cavitation problem. In order to hold cavity form and provide design reference for engineering applications, numerical simulation of natural cavitation induced by typical cavitors has been presented by using the commercial software FLUENT. Consequently, empirical formulas between typical cavitor parameters and cavity shape are obtained under the conditions of zero incidence and small cavitation number in the paper. Furthermore, the numerical results fit well with the experimental results.

Based on the time-dependent Reynolds-Averaged Navier-Stokes equations and Mixture-multiphase model, an approach was presented for solving venlilaled cavilaling flow by coupling natural cavitation model. The steady solutions of ventilated cavities have been obtained to establish the validation of the approach around a 3D axisymmetric body. The influence of ventilation rate was investigated on the shape and hydrodynamic characteristic of ventilated cavities. The results of simulation indicated that it is important for achieving a steady a supercavity to determine a reasonable gas supply rate.
