Tow-dimensional CFD simulation of bubbly flow in structured packings
Journal Title: Science Paper Online - Year 2008, Vol 3, Issue 12
Abstract
Basic research of bubbly flow in structured packings is of great importance for the development of novel gas-liquid mass transfer and reaction equipments. Simplified two-dimensional model was constructed and the volume of fluid (VOF) method was used to simulation the bubbly flow in structured packings. In the proposed model, two source terms were added into the momentum transport equation to describe the effects of surface tension and interface interaction. The results indicated that the bubbles rising in a chain oscillated and coalesced with increasing of gas inlet rate. The velocity of liquid surrounding the bubble increased and vortexes of different scale were observed. The velocity at a fixed point in liquid fluctuated more and more frequently as the gas inlet velocity increased.
