摘　　要：针对核电机组中的汽水分离器用波纹板,采用计算流体力学方法对不同结构波纹板模型进行了数值模拟,分析了波纹板内流场的特点,并与试验结果进行了对比.结果表明:数值计算结果与试验结果基本吻合,数值计算可以较准确地模拟波纹板中的流场;流动分离是造成波纹板压力损失的主要因素.Based on the model of differently-structured corrugated plates for moisture separators of nuclear power plant, numerical simulations were carried out by computational fluid dynamics （CFD） technique, so as to analyze the flow characteristics in the moisture separator, and to compare the simulation results with experimental data. Results show that the numerical simulation agrees well with the experimental measurements, proving the numerical way to be effective in simulation of relevant flow fields in moisture separators. The flow separation is found to the main cause leading to the pressure loss.
