Bottom blocked case

 A simulation with a refine mesh to simulate the experiment bottom blocked case is also conducted.

Experiment

Simulation with jadim-level set

 

For the bottom close case, the movement is  mainly led by the density differences. The final flow patterns are the same for the simulation and experiment.  The equilibrium time to arrive the final state is  similar with experiment and simulation. The movement is similar, however, same with the bottom open case, more dispersed phase appears in the simulation.
