3-D HEAT AND MASS TRANSFER AND MANIPULATION USING MICROWAVES

Saber M. Ali

Abstract


Investigation is made for three-dimensional heat and mass transfer using microwave power and hot air. Analytical and numerical approach of the microwave drying process is presented. The nonlinear system is solved numerically by finite difference techniques. Simulation is performed for a material of isothermal moisture contents and mass transfer analogue of temperature. The work is done for frequency of operation equals to 2.45 GHz. Key Words: Heat and mass transfer, Hybrid microwave drying, modeling, Nonlinear system, Energy balance, Power absorption.
