摘要
采用计算流体动力学(CFD)方法对AP1000非能动余热排出热交换器(PRHEHX)进行数值模拟,研究其流动与传热特性。对C型传热管束区采用多孔介质模型处理,同时考虑传热管内一次侧流体到管外二次侧流体耦合换热。通过计算获得不同时刻安全壳内置换料水箱(IRWST)内的温度场和流场分布以及传热管内流体温度沿流动距离的变化特性等参数。
Computational fluid dynamics （CFD） methodology is adopted to simulate the fluid flow and heat transfer characteristics of the passive residual heat removal heat exchanger （PRHRHX）. The C-type tube region is modeled by the porous media method. The coupled heat transfer rate from the primary side fluid to the secondary side fluid of the PRHRHX tube is calculated during the calculation. The secondary side temperature and velocity distribution in the in-containment refueling water storage tank （IRWST） at different times are analyzed. The primary side fluid temperature distribution inside the heat transfer tube is obtained.
