Effect of electromagnetic field on distribution of temperature, velocity and concentration during saturated flow in porous media based on Local Thermal Non-Equilibrium models (influent of input power and input velocity)
The work presents the effect of electromagnetic field on distribution of temperature, velocity and concentration during saturated flow in porous media. The simulations of electromagnetic field (mode TE10) are obtained by solving Maxwell's equations via the finite difference time domain method (FDTD). In addition, Darcy-Brinkman-Forchheimer's model are used to describe the pattern of fluid flow and intensity distribution in porous media where the finite control volume model and SIMPLE algorithm are used to solve these system of equations. The two energy equations for solid and fluid phases are proposed in model of Local Thermal Non Equilibrium condition (LTNE). The effects of input power of electromagnetic wave i.e. 500, 800 and 1600 W, input velocity i.e. Re-p 0.1, 0.5 and 10 were investigated. Distribution of temperature, velocity field and concentrated contaminants in transferred fluid inside of porous media were discussed. The results have also shown major issues on how high power of electromagnetic wave, significantly affects the distribution of temperature, concentration and the velocity field. (C) 2016 Elsevier Ltd.
