A Review on Liquid Spray Models for Diesel Engine Computational Analysis

Abstract

Spray technology is widely used in several engineering applications enabling the detailed control of combustion systems resulting in enhanced engine configurations and new technologies. A fundamental understanding of the spray breakup and atomization process enables a mathematical representation of its behavior allowing the development of physical models. Over the past two decades, three-dimensional computational fluid dynamics (3D CFD) solvers have played an increasingly important role in the engine research process providing new insights into specific complex phenomena. This report is aimed at illustrating the liquid spray models used in contemporary solvers primarily for automotive and aerospace engine applications. The available methodologies are reviewed, and their ranges of applicability are highlighted. Various unresolved issues in liquid spray-modeling are presented, mostly in the context of fuel effects, and hence providing areas of research opportunities.
