| Abstract: | A general mathematical model for heat and moisture transfer with improvement in mass,momentum and energy equations and with several transfer mechanisms to simulate simultaneous transfer of heat and mass in unsaturated media is developed.The volume average method developed by Whitaker is adopted and the limitation of the application of Darcy'S law to unsaturated porous media is discussed. |
