Numerical study of the wake acceleration effect using CFD approach

Chai, Xiang

Abstract:
A new drag force model was proposed to consider the wake acceleration effect. The proposed model is dependent on wake velocity. Based on a systematic CFD simulation, correlations were proposed to describe the velocity profile of turbulent wake. The proposed model was validated against the experimental data of bubble pairs and employed in the simulation of bubbly flow. It revealed better prediction accuracy than the existing models. It was also used to assess the bubble induced turbulence.
