Project description

Fuel takes the form of dispersed liquid droplets in several engineering devices. Turbulent combustion of droplet-laden mixtures has significant practical interests, but remains poorly understood. This is because of the complex interaction between many factors. These include fuel droplet evaporation, heat and mass transfer, fluid dynamics, and combustion thermo-chemistry.

Turbulent spray combustion occurs in fuel-efficient and low-emission combustion devices. Thus, we need a thorough understanding when we design and develop such devices.

This project will investigate monodispersed droplet-mist mixtures. We will simulate turbulent combustion of mixtures in spherically expanding flame kernels. We will carry out a detailed parametric analysis. This will help us to understand the effects of a variety of parameters on the flame structure in turbulent droplet laden mixtures. These parameters include droplet diameter, droplet number density and turbulent intensity.
