CFD Analysis of Biofuel (Cnsl Blended With Diesel) Run Diesel Engine

Abstract

The world is confronted with the twin crises of fossil fuel depletion and environmental degradation. The indiscriminate extraction and consumption of fossil fuels have led to a reduction in petroleum reserves. Petroleum based fuels are obtained from limited reserves. These finite reserves are highly concentrated in certain regions of the world. Therefore, those countries not having these resources are facing a foreign exchange crisis, mainly due to the import of crude petroleum oil. Hence it is necessary to look for alternative fuels, which can be produced from resources available within the country. The present paper investigates the use of the Cashew Nut Shell Liquid (CNSL) Biodiesel as a Alternative Fuel through experimental analysis of engine performance & CFD analysis. In this study, biodiesel derived from CNSL blended with diesel have been chosen for testing and analysis. Several engine performance tests and CFD analysis have been carried out and initial results have been tabulated. The experiments disclose that the use of blends of CNSL and diesel as a fuel reduces the overall diesel consumption and hence dependency on diesel. Among the blends tested against diesel (B10, B15, B20), the blend B20 (20% CNSL and 80% Diesel) proved to be superior, displaying better engine performance characteristics, in comparison with diesel and the other blends.
