Abstract: The finite volume method is used to numerically simulate the laminar heat transfer performances of a plate fin-and-tube heat exchanger surface with radially positioned slots and a plain plate fin-and-tube surface. It is found that at the identical pumping power or identical pressure drop, the performance of the slotted fin surface is much better than that of the plain fin surface, while under the identical mass flow rate, the performance of the slotted fin is inferior to that of the plain one, and where there is an enhanced heat transfer, there is a better synergy between velocity and temperature gradient.
