The model was developed to describe the flow behavior, distribution of concentration and distribution of temperature in a porous media. The magnitude of electromagnetic wave power has a substantial impact on the temperature of porous media. An increase in the electromagnetic wave power produces a higher porous temperature and enhances a larger temperature difference between solid and fluid phase. The high microwave power (1600 W), the most influence to distribution of temperature, flow fields and distribution of concentration of the fluid within porous media during saturated flow. High inlet velocity fluid (Rep = 10), the most influences to distribution of the temperature. During high microwave power implementation (1600 W), the Local Thermal Non-Equilibrium models is suitable for this testing this simulation. Our results show that an imposed electromagnetic field has substantial effect in altering the LTE between solid and fluid phases in porous media.
