Advanced Spray Research

The process of fuel/air mixture preparation via an atomizing spray controls combustion efficiency (hence CO2 reduction) and emissions formation in direct injected engines. Understanding of spray breakup is one of the weakest links in understanding of combustion. Professor Linne´s group has developed techniques to overcome experimental difficulties. We are investigating a sequence of flowfields, starting with the most basic and adding complexity in steps. Each step is taken intentionally to pull theorists further into the complexity of an atomizing spray; to fully evaluate dynamics and to stimulate the evolution of predictive models. We are collaborating with a number of leading theorists from around the world (not funded by this proposal) in order to ensure that we proceed in parallel with the appropriate level of model development. The proposed work will focus on very basic steady liquid sprays as they issue into air at one bar.
