Recent Research Highlights

High-temperature chemical kinetics

We explore the reaction mechanisms of fuel combustion by quantum mechanical and RRKM calculations, combusting flow simulations, and model optimization.  Our objective is to develop a comprehensive and predictive reaction model for the combustion of hydrocarbon fuels.

Soot formation

 

 

The yellowish luminous flame is the consequence of soot formation during the conversion of fuel to carbon dioxide.  Our work focuses on size-resolved and on-line characterization of soot particles (in collaboration with Professor Denis Phares) and detailed modeling of soot formation.

Nanoparticle synthesis and characterization

We study how nanocrystalline metal oxide thin films may be produced in combustion flames.  These particles are of interest to applications including gas sensing, nanocatalysis, photocatalysis, and solar cells.

Transport properties of nanoparticles

We are developing a fundamental theory of nanoparticle transport in dilute gases.  Topics of investigation include drag force, electric mobility, and diffusion coefficient.  Our aim is to obtain a unified theory of particle transport over the entire range of Knudsen number and particle material and shape.
