摘要
在采用准三维数值计算方法计算与分析一台双流程凝汽器的三维汽相流动与传热特性的基础上,针对由于冷却 水温度沿流向上升引起的汽流偏斜对传热特性的不利影响,提出一种利用导流板改善流动与传热特性的措施,通过计算证 实了措施的有效性。
The three-dimensional steam flow field and heat transfer behavior of a two-pass power plant condenser are analyzed by using a quasi-three-dimensional numerical simulation code. The results show that the cooling water temperature rising along its flow direction causes the steam flow deflection and in turn results in the deterioration of heat transfer performance of condenser. A approach to suppress the influence of steam flow deflection by means of a baffle is suggested and its effectiveness is confirmed by using numerical computation.
