Abstrakt:	The efficiency of plate heat exchangers (PHE) is extremely influenced by the various flowing conditions and heat transfer caused by the complex structure. Numerical simulation of PHE with low flux and high heat transfer was performed using Computational Fluid Dynamics (CFD). To prove that the simulation result was reliable, an experimental system based on the principle of equal velocity method was set up. Furthermore, the criterion equations of hot and cold fluid were derived. The heat transfer coefficient and flow resistance under various Reynolds numbers were analyzed and validated by experiment. Finally, we found that the realizablek-εoffered the best results. [ABSTRACT FROM PUBLISHER]
