| Abstract: | To reveal the variation patterns of flow structure,mass transfer and solid surface morphology in solid dissolution process under the effect of unsteady natural convection inside closed cavity,a two-dimensional mathematical model of solid dissolution process was established based on theories of dissolution kinetics and mass transfer.The finite element software COMSOL was used for numerical stimulation to investigate the effect of solid size on the flow,mass transfer and solid surface morphology.The results s... |
