Variational Iteration Method to Investigate The Initial Stage of Fuel Spray Penetration

The amount of penetration and evaporation of spray in combustion chamber has a basic role in engine efficiency. In recent years, numerical methods have been widely used to investigate spray penetration and evaporation in combustion chambers. While analytical methods cannot be applied to these problems, semi-analytical methods have the ability of solving nonlinear spray problems. In this survey, Variational Iteration Method (VIM) has been used to obtain the amount of penetration in the initial stage of fuel spray penetration. In this work, the simplest model for spray, without break up, has been investigated. The results show that this method can easily be applied to solve nonlinear equations of fuel spray.
