Abstract |
The thermal performances for the air side of the fins with elliptical winglet are investigated by numerical methods. The parameter which is the placed location of the elliptical winglet on horizontal distance from the tube center is selected for investigating. The numerical calculation is well predicting by the deviation between the numerical results and experimental results are within 5%-8%. The results show that this parameter affects the thermal performance of the air side. The best configuration in term of heat transfer is 0 mm horizontal distance (at the tube center). On this location also provides the maximum friction factor. Keywords- Heat transfer enhancement, CFD, Vortex generator and Winglet | |||||||||
