Influence of blending on the engine parameters and the Reynolds number

Abstract

A comprehensive analysis has been executed through dimensional analysis of Brake Thermal Efficiency. Blending of Gasoline with Ethanol, Methanol, and n- Butanol is known to us, but to what extent volumetric blending would be beneficial with gasoline has been studied in this paper. Using Buckingham π theory and dimensional analysis, we have found out the mathematical correlation of Brake Thermal Efficiency with some other variables, which influence the Brake Thermal Efficiency and other parameters of the Engine. Variation of Engine parameters and dependency of them with volumetric blending of alternative fuels is a major concern. Deriving the graphical variation of Reynolds number with different percentage of blend component, we can indirectly measure the turbulence and efficient propagation of flame of combustion. In this way, it is concluded whether blending is beneficial for point of view of proper combustion. Although we don't precisely defined the exact behaviour of blending components with Gasoline yet use some assumptions and relate the prototype of blending with derived mathematical correlations. E10, E15, E20, E25, E30, and E35 are used for comparative relationship with Gasoline. Some parameters are fixed; whereas others are changed accordingly to derived correlation.
