Numerical Simulation System for Analyzing Fuel Film Flow in Intake Port of Gasoline Engine

Abstract

A numerical model for film flow analysis was developed in which three-dimensional film flow behavior is treated as two-dimensional flow on curved surfaces, and the three-dimensional curved surfaces are projected onto imaginary flat planes to transform the three-dimensional equations into two-dimensional ones. This model is combined with a gas flow model and a spray model to form a numerical simulation system for analyzing fuel film flow in the intake port of gasoline engines. The qualitative validity of the system was verified by comparison with a fuel film flow formed in the intake port of a real engine. © 1995, The Japan Society of Mechanical Engineers.
