Kinetics of the removal of liquid from capillaryporous bodies in a fluidized bed under nonisotherma l conditions

  • E. N. Prozorov


A theory of mass transfer in capillary-porous bodies is proposed which allows for thermogradient transfer of a bound substance in liquid form. The results obtained are used to calculate the process of drying of ceramic articles in a fluidized bed.
