Abstract

The heat transfer enhancement of Longitudinal Vortex (LV) is a kind of technology with efficiency is high and resistance is low. The effective influence distance of LV is very important to extend this kind of technology in narrow rectangular channels under water medium. CFX10.0 is used to simulate this question, and three velocity components of water flow have been used to define the strength of LV. The results of this calculate method are compared with the experimental results of thermal infrared imager and phase doppler particle analyzer, and they are reasonable. In this paper range, the effective influence distance of LV is bigger than 33 times of Longitudinal Vortex Generators (LVGs) height.
