Two-phase bubbly flow simulation using CFD method: A review of models for interfacial forces

Large eddy simulations (LES) of dispersed gas-liquid flows for the prediction of flow patterns and its applications have been reviewed. The published literature in the last ten years has been analysed on a coherent basis, and the present status has been brought out for the LES Euler-Euler and Euler-Lagrange approaches. Finally, recommendations for the use of LES in dispersed gas liquid flows have been made.

Large Eddy simulation for dispersed bubbly flows : a review

The pressure distribution around a particle moving in a continuum is nonuniform. Integrating the pressure distribution over the surface one obtains a resulting force that is different from zero. As shown in Vol. I, Chapter 6.2, the different spatial components of the integral correspond to different forces: drag, lift and virtual mass forces. The averaging procedure over a family of particles gives some averaged forces which can be used in the computational analysis based on coarse meshes in the space. The purpose of this section is to summarize the empirical information for computation of the drag, lift and virtual mass forces in multiphase flow analysis.
