The breakup of a liquid stream into small droplets, commonly refer to as atomization, is important in many industrial applications such as combustion, pesticide spraying, fuel injection systems, cooling and the dispersal of biological agents. In advanced gas-turbine engines and other industrial burners, it is desirable to produce small liquid-fuel drops in order to increase evaporation and mixing rates. By clearly understanding mechanisms leading to the liquid atomization, it will be possible to accurately predict and control the resulting spray characteristics, namely the droplets size and distribution. This project aims to provide an exhaustive explanation of physical phenomena observed in liquid atomization and to characterize the resulting spray.
The goal of the research is to reveal and characterize the role played by the apping of wave sheets in the breakup process and the conditions leading to hole formation and disintegration of thin liquid sheets. Computational analysis and theoretical approaches will be combing to provide predictions of the resulting spray. The efficacy and accuracy of three-dimensional Navier-Stokes numerical simulations in the case of a large density ratio, typical of a realistic air/water system, will be improved through the combination of different numerical methods, such as adaptive methods, fast and robust interface tracking methods and Van der Waals equations to model the dynamics of very thin liquid sheets that cannot be undertaken by any reasonable spatial resolution. The research will enable a unique insight into the details of local flow fields leading to hole formation and disintegration which traditionally has not been possible to measure in experiments due to the time and spatial scales involved.
