摘要:
以纵流壳程换热器作为研究对象,对一种带状支撑纵流壳程换热器的壳程流体流动与传热特性进行了数值研究与分析.基于纵流壳程换热器的特性,建立了带状支撑结构的计算模型,对其流体流动与传热进行了数值计算,得到了壳程流场和温度分布等细观信息.对带状支撑换热器在不同几何参数及工况情况下的热力性能进行了综合分析,并将其特性与折流杆式支撑壳程特性进行了对比分析.研究表明,在相同的流动条件下,带状支撑结构壳程内,流体具有较强的湍动度,增大了的换热效果.
Abstract:
The shell-and-tube heat exchanger with longitudinal fluid flow in shell side was selected as the re-search object. The characteristics of fluid flow and heat transfer in shell side of shell-and-tube heat exchangerwith a ribbon support structure were studied numerically.Based on the characteristics of fluid flow and heat-transfer in shell side of heat exchanger,the periodic unit duct model was presented and adopted in the numeri-cal calculations for heat exchanger. The detailed information of the fluid flow and temperature field were ob-tained. The thermodynamic characteristics in shell side of the ribbon support structures with different parame-ters were analyzed comprehensively. In addition,the characteristics were compared with that of rod baffle heatexchanger,another heat exchanger with longitudinal fluid flow in shell side. lt is concluded that in the samecondition,in shell side with a ribbon support structure,fluid is of bigger turbulent intensity,which enhancesheat transfer.
