Analysis of Two-Component Fuel Spray with Multicomponent Fuel Modelunder High Pressure Injection Conditions（Second Report）

- Exponential correlation analysis of component concentration heterogeneity -

Abstract

The multicomponent fuel model, which estimates vapor-liquid equilibrium and physical properties of fuel mixtures, can represent heterogeneous fuel concentration distribution due to differences in evaporation characteristics of two-component fuel spray. In this paper, the concentration distribution characteristics of each component of a two-component fuel spray were measured by laser-induced fluorescence method and numerically calculated using the multicomponent fuel model with fuel injection pressure and ambient density as parameters.
