摘要:
考虑管壳式换热器壳侧筒体与折流板以及折流板与管子之间的间隙漏流,通过优化网格生成方法,对所建立的三维实体模型进行网格划分,用CFD软件FLUENT进行数值模拟,研究壳侧流体的流动与传热特性.经与实验对比,模拟结果与实验结果符合良好,两者压降的最大误差仅为10.4%,表明笔者所建立的模型具有较高的可靠性与准确性.笔者的建模方法及所得结果为评价现有管壳式换热器的性能提供了一定的参考价值.
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．
