Bubble Collapse Modelling

Please login with a confirmed email address before reporting spam

Hey everyone,

I am trying to model a bubble collapse which expands due to pressure difference. Materials are simply water and air. The intention is to capture the collapse of this bubble which then gives birth to a jet flow dividing the bubble. This process might take several steps before fully collapsing. The effects of this jet will be evaluated on a solid and flexible wall then. The initial conditions are set to default. Only the pressure of the bubble is set to be 100 times more than the environment. and the size of the bubble has been selected using Rayleigh equation.

However, for the first step, I need to choose the best multyphysics and model. I tried level set in laminar and turbulent. Been trying phase-field but no luck yet. I would appreciate your thoughts.

Thanks a bunch
