Abstract:

A 3-dimensional CFD model of two row finned tube heat exchanger with different fin patterns was investigated with FLUENT 14.5. Air side heat transfer and friction characteristics with three different types of fin having same global geometry have been investigated numerically. The fins were plain fin, slit fin and fin with vortex generator; they were numerically investigated with 5 different air flow ranging from 1 m/s to 3 m/s. the numerical results were compared with the experimental observations and high level of agreement were found between numerical and experimental results were found. Numerical results show that compared to slit fin, vortex generator fin have higher heat transfer performance. The vortex generator fin have lower pressure drop as compared to plain fin and slit fin.

Keywords:

- plain fin, slit fin, vortex generator, heat exchanger.
