Nano emulsified diesel - biodiesel blend selection through a MCDM technique

Abstract

Abstract The populace growth and their expectations for everyday comforts have prompted impressive utilization of renewable energy sources. Biodiesel blends and its nano emulsions is a decent option for engine application. This paper depicts the use of crossover Multi Criteria Decision Making for the determination of best nano emulsion for engine. Here, two MCDM techniques TOPSIS and VIKOR used to get the best Nano biodiesel emulsion. Diesel, Jatropha biodiesel blend of B10, nano emulsions of B10 with 25, 50 and 100 ppm of Al2O3 are used. The Brake thermal efficiency (BTE), Smoke, Carbon monoxide (CO), Carbon dioxide (CO2), Hydrocarbon (HC), Specific Fuel Consumption(SFC), excess Oxygen(O2), Oxides of Nitrogen (NOx) are considered as the assessment criteria. It shows that Diesel is positioned first for 0%,25%,50% and 100% load and fourth for 75% burden using AHP-TOPSIS and Diesel is positioned first for 25% & 50%, second at 0% & 100% and third for 75% load using AHP-VIKOR. Consequently, it is consistent that blending B10+50PPM and B10+25PPM biodiesel is recommended as a decent swap for diesel.
