The transient conjugate natural convection heat transfer in a differentially-heated cavity with partition of finite thickness and thermal conductivity are investigated numerically over the range Rayleigh number from 103 to 108, ratio that fluid 0.1 1000, dimensionless 0.05 0.2. An analysis obtained temperature contours profiles, time for onset stratification Nusselt shows effect is significant ...

Abstract The flow of reactive fluids into porous media, a phenomenon known as infiltration, is important in natural and engineered systems. While most the studies this area cover theoretical experimental analyses linear acid flow, present work concentrates on radial conditions from wellbore field finding exact analytical solutions to moving boundary problems uniform dissolution front. Closed-fo...
