Abstrakt

The present study aims at contributing to the development of the theory of surface evaporation and condensation phenomena from porous-capillary bodies. A mathematical model is described for unsteady-state processes in solids of uniform pore size and distribution.

The model is developed also for the solution of heat and mass transfer problems of the processes mentioned above. The investigations result in curves, depicting the change of the state parameters during the evaporation and condensation from the porous surface of uniform pore size varying corresponding to the relative humidity of carrier gas.

The paper deals also with the equilibrium conditions of the heat and mass transfer between gas, liquid and solid phase which interact by sorptive bonds.
