Enhancement of heat transfer using nanofluidsAn overview pe pipe heat transfer coefficient in hong kong

Feb 01, 2010The heat transfer coefficient of the nanofluid increases with an increase in the mass flow rate of the hot water and nanofluid. It was seen that the Gnielinski equation failed to predict the heat transfer coefficient of the nanofluid. Finally, it was also observed that the use of the oxide nanofluid has a little penalty in pressure drop.4.1.2.File Size 164KBPage Count 11
