Turbulent Two-Phase Flow Benchmark

This model shows how to solve a turbulent two-phase flow problem with the k-epsilon Turbulence Model closure model.

Industrial scale mold-filling problems often involve free-surface flows with a high Reynolds number, and a suitable turbulence model must be employed.

Liquid water is injected into a filling plate at a velocity of 16 m/s. The liquid density is 1000 kg/m3 and the viscosity is 0.001 Pa.s. The inlet channel width is 0.045 m, which results in a Reynolds number (for the liquid jet) of around 720 000. The liquid jet displaces the air and begins to fill the plate. The results are compared with numerical and experimental data.

Fluid density at 12 ms, blue area is water and red area is air.
