Spray & Atomization
Sprays have numerous applications in the automotive, pharmaceutical, agricultural, printing, and coating industries. The preparation of a well-mixed fuel and air mixture is critical to improving the efficiency of diesel engines and reducing the emission. During the fuel injection process in the combustor, the liquid fuel atomizes to very small-scale structures and droplets and forms a spray that eventually evaporates and mixes with the air. Understanding the atomization and spray formation is essential to control the spatial and temporal variations in the fuel/air mixing process and eventually enhancing the combustion progress in an engine. We develop high-fidelity computational models to resolve the atomization process at diesel engine relevant conditions.
