Synergistic Analysis of Thermal-Magnetic Coupled Fields Based on the LBM Method

This paper utilizes the Lattice Boltzmann Method (LBM) to conduct flow and heat transfer analyses on steady flow, pulsating flow, and thermal-magnetic convection models within flow channels filled with porous media. Based on the synergy theory of convective heat transfer fields, the synergy angles of velocity field and temperature field in typical cases of three models were calculated. Through the analysis of field synergy angles, the effectiveness of the synergy theory in evaluating heat transfer is verified. It is found that a smaller synergy angle corresponds to better heat transfer performance in convective heat exchange. The field synergy angle can be used as a quantitative indicator to analyze the heat transfer effect, and the purpose of enhancing or weakening heat transfer can also be achieved by controlling the field synergy angle.
