摘要

Abstract

By using a hybrid lattice-Boltzmann-finite-difference method (hybrid LBM-FDM method)

three-dimensional simulations of solutal interfacial convection were conducted for the process of CO

absorption into ethanol. A self-renewal interface model is adopted as an interfacial perturbation model. The simulation results revealed some three-dimensional features of the induced interfacial convection

such as the development of diverging cellular flowand Rayleigh plume-like convection in liquid phase. The concentration distribution of the simulation result is validated and found to be in well agreement with the Schlieren visualization results qualitatively. Additionally

the mass transfer enhancements by interfacial convection were investigated

via

both simulation and experiment for the absorption process

and the mass transfer is shown to be enhanced by the interfacial convection by about two-fold comparing with that by diffusion.
