Experimental studies on the heat transfer of Al-metal /water nanofluid system in a spiral tube

In this present investigation Al-metal/water nanofluid in different concentrations produced and the laminar flow convective heat transfer through spiral coil tube with constant temperature boundarycondition were examined. This study employed direct synthesis method to prepare Al/waternanofluid to serve as working fluid in test section. Result demonstrates Al/water nanofluid increase approximately 40% Nusselt number compared with base fluid. Furthermore the induced centrifugal force in the spiral coil tube has significant effect on the enhancement of the heat transfer
