Abstract
The longitudinal heat conduction is usually neglected during the analysis of cross-wavy (CW) primary heat exchanger. In this paper, an anisotropic heat transfer numerical model is proposed to analyze the local thermal field of primary surface plate affected by the small-scale longitudinal heat conduction. Moreover, a detached numerical model is used for simplifying grid and improving computational stability. It shows that the temperature distribution is non-uniform in the anisotropic heat transfer model. The small-scale longitudinal heat conduction makes the temperature distribution of plate become more uniform and enhances the heat exchanger performance. The temperature difference has little effect on the contribution of longitudinal heat conduction, while the contribution of longitudinal heat conduction increases with the increase of the inlet temperature and Reynolds number.
