The project propose to develop a predictive model for turbulent liquid atomization and in so doing take the first step towards advanced design tools for chemical energy conversion. The project will do this by conducing advanced experiments on a straightforward spray undergoing turbulent primary breakup: imaging of interior flows, two-pulse ballistic imaging of primary breakup, and measurements in the far field. Breakup will be thoroughly described via coupled ballistic imaging and direct numerical simulation. Based upon that description, a predictive model for primary breakup that is efficient enough for use in a much larger spray combustion code will be developed by adapting a simulation approach called one dimensional turbulence. The project will accomplish this development task by coupling experiment and theory, and by partnering with select international theory collaborators. The outcome will be a first step in the development of a genuinely predictive and efficient model for primary breakup, the weakest part of complete combusting spray models. This is one of the few practical routes to the energy-environmental revolution that society requires.
