Abstract |
|
Surface roughness is one of the first active techniques to be considered for the augmentation of forced convection heat transfer. It is necessary that the flow near the heat transfer surface should be turbulent so as to attain higher coefficient of heat transfer. However, energy for creating such turbulence has to come from the fan or blower and the excessive turbulence leads to excessive power requirement to make the air flow through the duct. In this experiment the air was blown by blower through a 45 and 60 angle of rib artificially manufactured on heated horizontal surface present in duct. This created more turbulence for improving heat transfer compared to plane surface. |
