MODELLING OF BUBBLE FORMATION WITH THE AID OF CFD

Abstract

Results of a numerical simulation of the bubble formation process obtained with the aid of computational fluid dynamics (CFD) approach are presented. A solution of the momentum balance (Navier-Stokes) equations was coupled with the volume of fluid (VOF) algorithm for tracking the gasliquid interface in 2D and 3D domains. The simulation results are compared with the experimental data regarding the influence of gas flow rate on the bubble formation regime and volume of the produced bubbles in a low-viscosity system (air-water). As the simulation results are in agreement with the experimental observations, the VOF algorithm is found to be a valuable tool for studying the phenomena of gas-liquid interaction.
