Abstract

Grey relational analysis of the multiple responses, including Reynolds number, Nusselt number, heat transfer (W), heat transfer coefficient (W/m2 K), and heat flux (W/m2), was done as part of experiments based on a Taguchi orthogonal array. The best parameter levels was calculated and selected based on GRA on basis of the Grey Relational Grade (GRG). An ANOVA has been used to identify factors that significantly contribute to the response based on grade. Experiments was conducted at the optimum predicted conditions (Al2O3) and the response was found as follows; Reynolds Number (592), Nusselt Number (2.5), Heat transfer (Q) (510), Flux (W/m2) (17.8) and Heat transfer Coefficient (W/m2 K) (394). The experimental value was found to be correlated with the predicted values of Reynolds number (610), Nusselt number (2.6), heat transfer (Q) (530), heat transfer coefficient (W/m2 K) (415), and heat flux (W/m2) (18.5), respectively. The experimental data were found to have an excellent knowledge under the recommended conditions. Our study is a preliminary step towards developing a substantially effective Al2O3-based base fluid to enhance the performance of the heat transfer process in a copper-based serpentine shape heat exchanger.
