Modeling New Drying Processes That Use Supercritical Fluids

Mathematical modeling is used to show that a rise in temperature intensifies both convective and diffusion transport. An intensification of convective transport is observed along with an increase in the consumption of carbon dioxide. The effect of convective transport in the free volume of a dryer and the boundary layer of its plate is especially noticeable at the first stage of supercritical drying. Raising the pressure has no appreciable effect on the rate of supercritical drying.
