Dispersed multiphase flows,including gas-particle(gas-solid),gas-spray,liquid-particle(liquid-solid) ,liquid-bubble,and bubble-liquid-particle flows,are widely encountered in power,chemical and metallurgical,aeronautical and astronautical,transportation,hydraulic and nuclear engineering. In this paper,advances and re-search needs in fundamental studies of dispersed multiphase flows,including the particle/droplet/bubble dynamics,particle-particle,droplet-droplet and bubble-bubble interactions,gas-particle and bubble-liquid turbulence interac-tions,particle-wall interaction,numerical simulation of dispersed multiphase flows,including Reynolds-averaged modeling(RANS modeling),large-eddy simulation(LES) and direct numerical simulation(DNS) are reviewed. The research results obtained by the present author are also included in this review.
Liquid-particle, liquid-bubble, and bubble-liquid-particle flows, are widely encountered in power, chemical and metallurgical, aeronautical and astronautical, transportation, hydraulic and nuclear engineering. In this paper, advances and re-search needs in fundamental studies of dispersed multiphase flows, including the particle / droplet / bubble dynamics, particle-particle, droplet-droplet and bubble- gas-particle and bubble-liquid turbulence interac-tions, particle-wall interaction, numerical simulation of dispersed multiphase flows, including Reynolds-averaged modeling (RANS modeling), large-eddy simulation The research results obtained by the present author are also included in this review.
