| Abstract: | This paper puts forward two new baffle plate structures of T baffle plates and Y baffle plates based on the structure characteristics and properties of current tube-and-shell heat exchanger. The geometry model and finite element model of tube-and-shell heat exchangers with T baffle plates and Y baffle plates are created through ANSYS Workbench. The fluid flow and heat transfer performance in shell pass at different inlet fluid velocities are analyzed through Fluent. For tube-and-shell heat exchanger with Y baffle plates, the effects of included angle of side baffle plates on the heat transfer performance in shell pass of the exchanger are studied. The structure parameters of T baffle plates are optimized using the multi-objective optimization tool Design Exploration. |
