Abstract

To have the maximum benefits of nanofluid for high film coefficient, like hybrid composite materials in the material’s revolution, the hybrid nanofluid was prepared and its performance was realized by experimentation. In this investigation, the prepared Al2O3 (50%) – CuO (50 %)/water hybrid nanofluid was used as a coolant for making pen barrel in injection moulding machine. For experimentation, the three process parameters viz., Volume Fraction (VF), Volume Flow Rate (VFR) and Temperature (Temp) were controlled and optimized by using Taguchi’s L9 orthogonal array to yield the maximum film coefficient. To optimize it, total nine different experiments were conducted by controlling these factors. All these three parameters were considered in three levels. Regression equation was established to predict film coefficient by incorporating independently controllable process parameters. Based on the optimization result, it was found that the high film coefficient was achieved at 0.2 %, 6 LPM and 35 °C of VF, VFR and Temp of hybrid nanofluid respectively.
