Investigation of the Dielectric Behaviour of Propylene Glycol (100) Dispersed With Graphene Nano Powder to Determine the Optimal Conditions Using Response Surface Methodology

Abstract

Response surface methodology (RSM) was used to study the dielectric behavior of a Propylene Glycol-Graphene Nanopowder nanofluid. This study used 3-11 mm distance and 2.77-3.13 kV breakdown voltage. The goal is to find the best prediction model and solution. The lack of consistency between laboratory behavior and real-world applications and the statistical-mathematical investigation of modelers' performance, contrast, and motives prompted this study. Two models are tested: linear and 2FI. Investigating and evaluating these modeling functions' statistical properties is new to the area. The 2FI model depicts nanofluids twice as accurately as other models, according to statistical analysis. Model evaluation indicators include R2, C.V%, and P-value. In order, the 2FI model indices are 0.9818, 8.74 %, and 0.0001. Nanofluids should have 1256.877 electrical conductivity at 11 mm and 2.77 kV breakdown voltage.
