Numerical simulation and research of fluid flow and heat transfer in the shellside of rod baffle heat exchanger with longitudinal flow of shellside fluid
In the paper, the rod baffle heat exchanger with longitudinal flow of shellside fluid is simplified according to its structural characteristic and the periodic unit duct model is established.By employing commercial CFD software FLUENT, the numerical simulation of models for different media,at different Reynolds numbers and different rod-baffle pitches was carried out.The results were analyzed and compared to obtain the detailed characteristics of fluid flow and heat transfer in the duct and the optimal range of rod-baffle pitch values, which provides some reference for the research and application of heat exchanger with longitudinal flow of shellside fluid.
