ARTICLE INFO In this new era, a nanofluid serves as energy efficient fluids over traditional heat transfer fluids. In this paper the water based metal oxides Al 2 O 3 , TiO 2 , and SiO 2 are analyzed as a three different nanofluids using Taguchi methodology. Numerical investigations for heat transfer coefficient were done at three levels of four different parameters like Reynolds Number, Tube Diameter, Nanoparticle Concentration, and Nanoparticle Diameter Size. For experimental analysis L9

Geometrical configuration consist circular cross sectional pipe of one meter length and forced turbulent internal flow with constant temperature (350K) wall condition. The predicted experiment shows up to 42% increment in heat transfer coefficient by using nanofluid flow than conventional fluid water. Furthermore randomly selected combinations of parameters were compared with actual results of experiments and it shows that less error and successfully tuning of Taguchi method for prediction of heat transfer coefficient.
