Abstract A computational model is established to investigate the effects of a periodic gust flow on wake structure ventilated supercavities. The effectiveness validated by comparing with available experimental data. Benefited from this numerical model, vertical velocity characteristics in entire field can be easily monitored and analyzed under action generator; further, unsteady evolution param...

The nonlinear and multi-factor-dependent characteristics of the hydrodynamic forces acting on the aft body of a supercavitating vehicle are investigated using computational fluid dynamics (CFD). The CFD model of natural supercavitating flow is first verified and validated upon the supercavitating flow around a cavitator in the shape of a circular disk. Then the model is used to simulate the sup...
