Field Synergy Principle Base on Divergence Equation for Heat and Mass Transfer of Porous Media

Abstract:

According to field synergy principle, analyzes the relationship of the effect for heat transfer with mass transfer in porous media. Using the divergence equation, express the degree of gas phase velocity vector and temperature gradient velocity in the process of heat and mass transfer, and the field synergy angle θ play an important role in heat and mass transfer either global or partial. In the result, the heat and mass transfer would be constrained by each other while πθ>π/2, and be promoted whileπ/2>θ0, and be independency while θ=π/2. The divergence equation of field synergy principle present the method of strengthen the heat and mass transfer in porous media.
