Numerical Simulation of Multiphase Flow and Interface Mass Transfer on Particle Scale

Pp. 40-110 (71)

Abstract

More and more attentions have been paid to better understanding of the mechanisms of multiphase flow and interphase mass transfer on the mesoscale (particle scale), namely about solid particles, bubbles and drops. The behavior of particle swarms and effects of surfactant are subsequently studied to approximate real industrial processes. Besides, the sub-particle scale Marangoni effect, induced by interphase mass transfer, is also studied for seeking measures of mass transfer enhancement. The computational fluid dynamics and computational transport principles are being developed into reliable and efficient tools for improving the macroscopic performances of unit operations and process equipments.
