Abstract

Finite volume based modeling of ventilated supercavity pulsation and its mitigation via a priori modulation of ventilation flow was investigated. Simulated pulsation was numerically achieved, as was mitigation of pulsation via sinusoidal modulation of the ventilation flow. In addition to confirmation that the numerical approach is sufficient to capture mitigation, it was found that modulated ventilation, without altering the mean ventilation mass flow rate, results in altered cavity size, pressure, and closure condition.
