Overview

Sprays, sandstorms, rainfall, and cavitation are all examples of two-phase flows. The study of multiphase flows focuses on analyzing and predicting flows where any combination of solid, liquid, and/or gaseous substances are present. This is important for designing an aerosol inhaler to deliver a precise dosage of medicine, understanding the dispersal pattern of powdered pesticides, or obtaining good fuel/air mixtures inside internal combustion engines.

Research Interests

Fuel injector modeling (gas and liquid) for rocket and air-breathing engines; injector/chamber compatibility for rocket applications; modeling of spray and particulate dynamics.

Current Research Projects

Modeling Spray Dynamics by Maximum Entropy Moment Closure

The purpose of this work is to develop a statistical method of solving the spray flow problem. The approach is to derive and solve a set of Eulerian moment transport equations for the quantities of interest in the spray, coupled with the appropriate gas-pahse (Eulerian) equations.
