CONTRIBUTION TOWARDS THE DEVELOPMENT OF MODELING METHODS FOR TURBULENT SPRAYS
Deepak M. Kirpalani, Andrea E. Spencer · 2008
A population balance approach with a novel cascaded breakage kernel was developed to study turbulent sprays. The proposed cascaded approach applies wave breakup theory to the primary liquid core and a turbulent breakup that recognizes multiple droplet breakups can occur due to one eddy in the far field of the spray. Two-dimensional (2-D) axi symmetric numerical simulations were performed to predict the evolution of a turbulent spray with the proposed cascaded population balance approach in a computational fluid dynamics (CFD) framework to visualize the predicted spray. The results were evaluated by comparing intact length of the liquid core and droplet Sauter mean diameter distributions in the far field of the spray with experimental droplet measurements and were found to be in good agreement.
