Abstract
Heat transfer can be improved by longitudinal vortex (LV) generated by longitudinal vortex generators (LVG) in narrow rectangular channel. The CFX10.0 is one kind of CFD commercial software, used to simulate vapor-liquid two-phase medium. The results show that the edge of narrow rectangular channel may be cooled by LV generated by LVG, and the flow velocity is improved in the center of channel, so the heat flux of hot plate can be improved obviously. At the same time, the mixing of cold and hot fluid may be enhanced by LV. Comparing with smooth channel, the efficiency of heat transfer is increased obviously with resistance of flow increases properly within the range of this paper.
