Against single-row finned tubes used in 1 000 MW air-cooled condensers(ACC)
the flow and heat transfer performance of finned tubes was calculated by computational fluid dynamics(CFD)software under different head wind velocity distribution conditions.The effect of head wind velocity distribution on heat transfer coefficient at air side of the single-row finned tube was analyzed.The results show that
the distribution of head wind velocity decreased along the vapor flow direction can enhance the heat transfer coefficient of finned tubes
and it was beneficial to heat transfer.The parabolic distribution was superior to the linear distribution.
