摘要
为了研究当前电力工程设计中复杂的流动、传热问题,采用计算流体动力学(Computational Fluid Dynamics,简称CFD)技术分别针对火电机组小机排汽、直接空冷以及烟道等三个系统进行了研究,详细阐述了计算目的、计算域和边界条件的设置,得到了各系统内部流场的流动特性。从各方面的应用可以看出,CFD仿真技术在电力工程设计领域存在着广阔的应用前景。
In order to study the complex flow and heat transfer in power engineering design,computational fluid dynamics （CFD） technology was used to study exhaust steam system of steam feed pump,direct air cooling system and flue system.The calculation purpose,calculation domain and boundary conditions are described in detail,and the internal flow characteristics of each system is obtained.From all aspects of the application,CFD technology has a wide application prospect in power engineering design field.
