Two different types of nanoparticles "namely Al2O3 and SiO2" suspended in distilled water with two particles concentrations are successfully prepared and experimentally tested. Both numerical and experimental results show a good enhancement in heat transfer by using vortex generator with base fluid. A significant heat transfer enhancement is observed by using compound vortex generators and nanofluids accomplished with a moderate increase in the pressure drop. High gradient in wall temperatures is monitored when the water is replaced by nanofluid particularly at higher volume fraction. A small deviation has been seen between the present numerical and experimental results. � 2015 Elsevier Ltd. All rights reserved.
