摘 要：The impact of drop on a liquid pool can entrap bubbles and splash smaller *** bubbles can dissolve and transfer gas into the pool,while the droplets can generate *** studies on drop impacts have neglected the effect of vorticity on the *** were able to reproduce the large scale dynamics of the drop entering the ***,recent results have demonstrated that the vorticity produced at the air-liquid interface plays a critical role in explaining the complex dynamics of splashing and air *** focus here on the dynamics of the air bubble entrapped just after contact between the drop and the *** show the role of vorticity in producing a large range of different bubble shape,including toroidal bubbles,and bubbles containing a liquid droplet
