摘  要:
A mathematical model of simultaneous heat and moisture transfer is proposed for prediction of moisture and temperature distributions in a porous solid during drying. Both temperature and moisture distributions in a potato slice, as an representative material have been simulated by using the finite difference method. The results were compared with experimental ones and showed a good agreement between them.
