The Fluent software was employed to carry out three dimensional numerical simulation on heat transfer performance of rectangular eccentric corrugated fin-and-oval tube heat exchangers with five different corrugated inclination angles

with facing velocity ranging from 0.5m/s to 4m/s.The results indicate both the facing velocity and corrugated angle can affect such indexes as Nusselt number on surface of the rectangular eccentric corrugated fin-and-oval tube heat exchangers

average differential pressure loss and finned tube heat transfer performance influence factor.The comprehensive heat transfer performance of the rectangular eccentric corrugated fin-and-oval tube heat exchangers turned worse with an increase in corrugated inclination angle.Through analyzing variation of the Nusselt number Nux on finned tube surface

we can predict that properly increasing the front windward corrugated inclination angle and reducing the rear area corrugated inclination angle not only can enhance the heat transfer but also can reduce the resistance loss.Furthermore

the reliability and validity of the simulation model were checked by experimental examination

and the simulation results can provide some practical and reliable theoretical basis to the research of finned tube heat exchangers.
