Heat Transfer Characteristics of a Solid-Liquid Mixture Rotation Baffle Heat Exchanger

In this paper, three-dimensional numerical simulation was performed for a solid-liquid mixture rotation baffle heat exchangers (SLMBH). The vector field, temperature field and stream line inside the solid-liquid static heat exchanger were studied. The influence of Reynolds number, baffle interval and tube radius on the heat transfer was analyzed. The results have been compared with the results that of smooth tube. It shows that with the increase of the baffle interval or the tube radius, the heat transfer could be enhanced in mix section. And the numerical results were also discussed based on the viewpoint of the Field Synergy Principle. The reason of the heat transfer enhancement in the SLMBH is that the intersection angle between velocity and temperature gradient is increased.
