A interface formation in two-phase flow problems
Original language description
the objective of the paper is a numerical investigation of the multi-phase unsteady flow problem representing the formation and kinetic of bubbles. The mathematical model is given by the equation system used commonly for the three-dimensional viscous unsteady laminar flow problem. Shapes and forms of the phase-interface between gas-liquid depend strongly on the used grid resolution. Generally for various grid resolutions, different bubble formations were found. However, the volumetric fraction of the gas in the mixture was identical up to particular time. In advanced time, different progress of the gas decomposition was identified and the gas amount in the mixture was significantly lower in respect to the theoretical assumption. Furthermore, kinetic and bubble formations were investigated in liquids with various kinematic viscosity. It was found that kinematic viscosity could evidently influence the bubble formation, size and shape, but not a capability of the liquid to capture gas in the liquid as it can be assumed.
