Abstract:
The three dimensional flowing field of steam in direct air cooling exhaust ducts was simulated via computational fluid dynamics （CFD） software called fluent for Datong 600MW power generating unit. Results show that the pressure drops of the steam flowing through distribution manifolds are not the same, so as the mass flow. The studying results can provide assistance for the system structure＇s optimal design of direct air cooling exhaust ducts. Figs. 3, table 3 and refs. 3.[著者文摘]
