With the CFD calculation software FLUENT, numerical simulation has been conducted to study the surface flow and heat transfer in inclined wave fin-and-tube heat exchanger, including uniform angle wave fin and inclined increase-angle wave fin. Velocity field, pressure field and the distribution of temperature field on the air side of fin surface were obtained. Heat transfer performance of the two kinds of fin were discussed and the curve of both heat exchange and pressure drop related to the inlet velocity were analyzed. The results indicates that in the same conditions, heat transfer effect is better than uniform angle wave fin. When the inlet velocity is 4 m/s ,the heat transfer of inclined increase-angle wave fin is about 1.1 times higher than that of uniform angle wave fin meanwhile the pressure resistance is as much as around 1.2 times, which provides a theoretical basis on heat transfer enhancement of wave finned tube.

The Relationship

According to the periodic structure of the plate-fin heat exchanger, 3D model of the heat exchanger is established which simplifies the computation amount of the numerical simulation on flow field and temperature field. The relationship of fluid velocity, temperature, pressure drop and heat transfer coefficient is analyzed. The flow and heat transfer characteristics can be well predicted. Based on the simulation results, the conclusion makes reference to the design of plate-fin heat exchanger.
