Analysis and Calculation of the Best Center of Mass for Supercavitating Projectile
Journal of Sensors, Volume 2022, Issue 1, 2022., 2022 Currently, the supercavitating projectiles mostly rely on experience or experimental results to test the shape of the projectile; however, the cost of the experiment is relatively high, and there is no specific criterion to judge whether the underwater projectile is stable.

Bow and Stern Control Surface’s Effectiveness and Influence on Supercavity
Journal of Sensors, Volume 2021, Issue 1, 2021., 2021 The numerical model of supercavitating flow field was established based on multiphase model, cavitation model, and turbulence model. The model was employed to simulate the supercavitation flow for the supercavitating vehicle with two types of control surfaces: bow rudder and stern rudder.

Experimental Study of Vapor Supercavitation Suppression of Capillary Outlet Jet Noise
Journal of Mathematics, Volume 2021, Issue 1, 2021., 2021 The degree of bubble bursting at the inlet of an evaporator is the key factor to determine the size of the injection noise at the capillary outlet. In this study, by using the theory of cavitation dynamics, the transition tube between the capillary and evaporator is improved to suppress the bubble bursting at the entrance of the evaporator, so as to ...
