摘要
The flat wave-finned tube is a kind of commonly used fin-tube by the direct air-cooled condenser. It is of great importance to investigate the flow and temperature fields outside the flat wave-finned tube for the design and running of the direct air-cooled condenser. The air flow and temperature fields were numerically simulated at different apex angles of tube banks as well as different air temperatures and inlet air velocities. The variations of Nu and friction coefficient f with Re and apex angles of the tube banks were obtained. The results show that the apex angle of the tube banks affects the flow and heat transfer performances and the larger the apex angle, the better the air cooling effect.
