- Abstract:
-
In this paper,a three—dimensional numerical model is presented to simulate the characteristics offluid flow and heat transfer in shellside of shell··and··tube heat exchanger by using CFD code FLUENT soft--ware,in which the baffle-shell leakage and the baffle-tube leakage are considered.compared with the experi·ment。it can be found that the simulated results agree with the experimental results well,the maximum relativeerror of the pressure drop is only 10.4%.and the model reliability is validated.The modeling method and nu·merical results are helpful for evaluating the performance of present shell-and—tube heat exchanger.
