Numerical Analysis of Spray Formation Process Using a Swirl-Type Injector

Abstract

Numerical analyses by DDM (Discrete Droplet Model) are carried out to clarify the effect of initial conditions on the fuel spray formation process using a swirl-type injector. Two kinds of initial conditions are tested; one is empirical expressions and the other is the results obtained using VOF model that is used to simulate the two-phase flow inside the injector to give the liquid film formation process outside the nozzle.
