Abstract In the current paper, the behavior of zinc oxide/SAE50 nano lubricant as a part of the new generation of coolants and lubricants is examined using response surface method (RSM). The data used in this study were viscosity at dissimilar volume concentrations (0–1.5%) and temperatures (5–50 °C) for dissimilar shear rate values. Therefore, sensitivity analysis based on variation of nanoparticle (NP) concentration and temperature was also implemented. The findings revealed that enhancing the volume fraction (φ) exacerbates the viscosity sensitivity to temperature. Given the noteworthy deviance between the experimental viscosity and the data forecasted by existing classical viscosity correlations, a novel regression model is gained. R2 and adj-R2 for this model were calculated as 0.9966 and 0.9965, respectively, which represent a very good prediction with a standard deviation of 3%.

AbstractDesign of Experiment is one of the extensively used method for experimental study of many manufacturing processes in engineering. In welding, Design of Experiments are widely used to develop a mathematical relationship between the welding input parameters and the output variables of the weld joint in order to determine the welding input parameters that lead to the desired weld quality. In the present study, a review is made on Response Surface Method based Design of Experiments that have been employed for various welding processes by other researchers. This study predominantly focuses on the usage of Response Surface Method in Welding.
