Abstract: Based on the bow baffle, the same working conditions are set. The FLUENT software is used to simulate the flow and heat transfer performance of the shell, fluid and heat transfer of the three baffle plates of curved, spherical and arched shapes. and the pressure drop and heat transfer coefficient of the shellandtube heat transfer with three types of plate are compared and analyzed. By comparing the heat transfer performance, pressure, temperature and velocity nephograms of the three plate heat transfer, the reasons for the difference in heat transfer performance are analyzed. The research results can provide reference for the design and heat transfer enhancement of the shell and tube heat transfer baffle, which has certain engineering practical significance.
