完成了新型热交换器的传热与流动性能实验研究,并与同规格下的弓形折流板热交换器性能进行对比.建立了简化的壳程计算模型,分别对弓形折流板热交换器和新型纵流式热交换器进行数值模拟,获得了2种热交换器壳程内部的流动分布、温度分布和压力分布,并将模拟结果与实验数据进行了对比.实验及模拟结果表明,新型热交换器温度分布均匀、流动死区少、壳程压降低,综合性能远高于折流板式热交换器.
完成瞭新型熱交換器的傳熱與流動性能實驗研究,併與同規格下的弓形摺流闆熱交換器性能進行對比.建立瞭簡化的殼程計算模型,分彆對弓形摺流闆熱交換器和新型縱流式熱交換器進行數值模擬,穫得瞭2種熱交換器殼程內部的流動分佈、溫度分佈和壓力分佈,併將模擬結果與實驗數據進行瞭對比.實驗及模擬結果錶明,新型熱交換器溫度分佈均勻、流動死區少、殼程壓降低,綜閤性能遠高于摺流闆式熱交換器.

An experimental study on the shell side flow and heat transfer of a new type shell and tube heat exchanger was conducted ,and comparative research of a segmental baffle heat exchang‐er with the same specifications was made .Then simplified shell side computational models of the two heat exchangers were created for numerical simulation ,temperature ,flow and pressure dis‐tributions were obtained ,and the simulation results were compared with the experimental data . Experimental study and numerical simulation results show :the new longitudinal‐flow heat ex‐changer has uniform temperature distribution ,small flow dead zone ,low shell pressure drop ,and combination property is much higher than segmental baffle heat exchanger .
