Numerical Research on Heat Transfer Characteristics of Surface Indirect Air Cooled Radiator for Boiler Water Pump Powered by Steam Turbine

To solve actual engineering problems,the flow and thermal characteristics of air cooling tower used indirect air cooled radiator under natural draft is simulated and analyzed by using the numerical heat transfer (NHT) software called FLUENT.The influence of different wind speeds on the natural draft rate of the tower and heat transfer rate of air cooled radiator are identified.It offers a theoretic foundation for the optimal design of indirect air cooling system.
