摘　　要：通过合理简化,建立高压给水加热器(下面均称为高加)过热段的实体模型。用大型CFD(computational fluid dynamics)软件FLUENT对高加过热段进行数值模拟。实验结果表明,正三角形布管方式的传热性能优于转角正三角形布管方式的传热性能。By simplified, Designed physical model for desuperheating zone of the High Pressure Feed- water Heater. Numerical simulations for the desuperheating zone of the High Pressure Feedwater Heater are carried out using the physical model with the CFD （ computational fluid dynamics） soft- ware FLUENT. The result indicates that the positive triangle type of pipes is better than the reverse type of pipes on heat transfer capability.
