A flow simulation in the foaming process
Original language description
This paper deals with unsteady three-dimensional numerical calculations of the two-phase flow problem represents a gas bubble formation in the liquid in the container with the specific size. For calculations, the Volume of Fluids approach is adopted to resolve the shape of bubbles and their dynamics. The liquid phase is a mixture of water-ethanol and the gas phase is considered as air. The problem is treated as isothermal. The study is still limited to the lower flow rates at which bubbles are created and rising separately without any interaction, merging etc. However, this particular problem still required finer mesh especially in the domain in which bubbles are formed. The current results showed that air bubbles have a form of the ellipsoid and after they reach the liquid surface, they are moving towards to the side walls along this liquid level. This fact is interesting from the view of the foaming process and for the other investigation of the bubble behaviour at this phase interface. The flow study is calculated parallel using compressible multi-phase flow solver.
