Computational Fluid Dynamics Study on Droplet Size of Kerosene Fuel

Abstract

This article provides numerical simulation of Computational Fluid Dynamics study on droplet size for kerosene fuel. Fine spray with homogeneous mixture of fuel and air during the injection process is expected to be promising for optimisation of combustion processes in order to achieve high efficiencies and emissions as low as possible. Study on atomization and pressure swirl atomizer will be carried for droplet size affection factors. Numerical study of computational fluid dynamics applying Navier-Stokes equation will be conduct by using Gambit and FLUENT software to observe droplet size such as Sauter Mean Diameter (SMD) for kerosene fuel using 2D Discrete Phase Model with 2D axisymmetric and particle diameter for kerosene fuel using 3D Discrete Phase Model with 30° swirl dominated.
