Fuel spill analysis during refueling​（Gas-liquid two-phase flow analysis）

By coupling the airflow analysis function using the Finite Volume Method (FVM) with liquid analysis using MPS, gas-liquid two-phase flow can be efficiently analyzed. When refueling, the inner air is removed from the tank by the breather tube. In this simulation, we can see that when the refueling flow rate increases, the air couldn’t be removed and the fuel flows backwards.
