Air Entrapment

The air entrainment model in FLOW-3D CAST is used to estimate the amount of entrapped air occurring in metal casting systems, such as gravity-poured casting processes. It is based on simple physical mechanisms, which means it can also be used to estimate the amount of entrained air occurring in other metal casting systems, such as high pressure die casting processes. Recent additions of even more physical details in the model allow entrained air, which is assumed to be in the form of bubbles, to be modeled as rising in the surrounding liquid metal because of buoyancy forces and even leaving the liquid if it reaches a free surface.
