Abstract

To study the influence of side-direction ventilation on the surface loads of a revolving body during water entry, based on the VOF (volume of fluid) model and the Realizable k-ε two-layer turbulence model, the numerical prediction of the flow field evolution and analysis of the surface load characteristics when a side-direction ventilated revolving body into the water at a low-speed are carried out. By comparing the cavity shape between the numerical predictions and the experimental results, the validity of the numerical method is verified. The effects of different ventilation rates on the cavity shape, the flow field evolution, and the surface load characteristics are then analyzed. The results show that ventilation changes the process of the cavity evolution and the pressure on the sidewall surface of the revolving body. With the effect of ventilation, the time when the first cavity falls off is delayed, and the ventilation gas flows to the area behind the cavitator, which improves the negative pressure situation behind the cavitator. The ventilation gas forms an obvious vortex structure near the spout, which then merges with another vortex formed by the cavitator at the cavity wall, leading to an increase in the vortex intensity in the middle of the cavity. With the increase of the ventilation rate, the closure time of the cavity becomes later, the volume of the cavity gets bigger, and the cavity near the tail of the revolving body is less likely to fall off. Compared to the non-ventilation situation, the ventilation will reduce the fluctuations of the surface loads. The greater the ventilation rate, the less the surface load fluctuations are. In general, the side-direction ventilation improves the flow field and the surface load characteristics of the revolving body during low-speed water entry.
