Numerical simulation on ventilation rates of ventilated supercavity

LU Jing,ZHANG Jia-zhong(School of Astronautics,Harbin Institute of Technology,Harbin 150001,China)  
Some problems about ventilation rates of the ventilated supercavity are investigated using the theoretical analysis,numerical simulation and mechanical test.Numerical simulation of the ventilation rates of ventilated supercavity in small cavitation number are studied using the commercial software Fluent6.3.The influence of the natural cavitation number and Froude number on ventilated coefficient as the ventilated cavitation number is invariable analyzed using results of the numerical simulation,and are proved using the experiment data.It can be concluded that the ventilated flux and ventilated rate increase as the natural cavitation number and Froude number are increased.The simple relation of ventilated rate and the natural cavitation number and Froude number are gained.
