Mathematical modelling was used to describe the course of convective drying of a ceramic body. The procedure is based on the assumption that the ceramic body comprises a binary mixture of incompressible components in which the moisture transfer is due to diffusion and heat conduction. The respective balance and constitutive equations are solved for the initial and boundary conditions defining the operation of convective body drying. Solutions of the equations provided models of convective body drying both involving and not involving thermodiffusion.
