Modeling Viscosity and Density of Ethanol-Diesel-Biodiesel Ternary Blends for Sustainable Environment

TLDR: In this paper, the density and viscosity of 30 different ternary biodiesel blends were investigated at 15 and 40 °C, respectively, and the prognostic ability and precisions of these developed models were assessed statistically using absolute percentage error (APE) and Mean Absolute Percentage Error (MAPE) The MAPE of 0045% and 0085% for density model and 185, 141, 348%, 348% and 227, 185, 185%, 185, 350%, 350% for viscosity model were obtained on % volume and % mass basis.

Abstract: Rapid depletion in fossil fuels, inflation in petroleum prices, and rising energy demand have forced towards alternative transport fuels Among these alternative fuels, diesel-ethanol and diesel-biodiesel blends gain the most attention due to their quality characteristics and environmentally friendly nature The viscosity and density of these biodiesel blends are slightly higher than diesel, which is a significant barrier to the commercialization of biodiesel In this study, the density and viscosity of 30 different ternary biodiesel blends was investigated at 15 °С and 40 °С, respectively Different density and viscosity models were developed and tested on biodiesel blends soured from different feedstock’s including palm, coconut, soybean, mustard, and calophyllum oils The prognostic ability and precisions of these developed models was assessed statistically using Absolute Percentage Error (APE) and Mean Absolute Percentage Error (MAPE) The MAPE of 0045% and 0085% for density model and 185%, 141%, 348% and 227%, 185%, 350% for viscosity models were obtained on % volume and % mass basis These developed correlations are useful for ternary biodiesel blends where alcohols are the part of biodiesel blends The modeled values of densities and viscosities of ternary blends were significantly comparable with the measured densities and viscosities, which are feasible to avoid the harm of vehicles’ operability
