This course, Spray Theory, provides an overview of the physics of liquid atomization, spray formation and propagation. Students will be introduced to theoretical models pertaining to jet breakup and drop formation, as well as the application of multiphase models for studying spray transport. The course will also present an overview of the design aspects as they pertain to spray nozzle and atomizers and discuss potential applications in combustion systems. Theoretical modeling of drop formation and atomization, drop size distribution models, and spray applications will be discussed. Experimental evidence and techniques for interrogating sprays will also be presented.

[Applications]
After this course, students will be able to apply the theoretical models of jet breakup and drop formation to various applications, such as spray combustion and spray drying. They will also be able to understand the physical processes underlying each application and the design process for each application. Additionally, students will be able to use the stochastic description of the spray formation and propagation process to understand the physical origins of drop size distributions. Finally, students will be able to use the multiphase transport framework for studying spray propagation.
