摘　　要：本研究对管壳式换热器进行数值模拟,通过对换热器的壳侧和管侧烟气流速做出改变,得到对应组合状况下的换热系数和壳侧的压降,最后比较换热器综合性能评价指标k/Δp,获得最佳管侧和壳侧烟气流速组合,使换热器达到较高综合性能。Numerical simulation of shell and tube heat exchanger was carried out.The heat transfer coefficient and pressure drop on the shell side were obtained by changing the flue gas velocity on shell side and tube side of heat exchanger.Finally,the best combination of pipe side and shell side flue gas velocity was obtained by using the comprehensive performance evaluation index of heat exchanger to achieve high comprehensive performance.
