Combustion and Energy Systems

LES of reacting spray jets


The Combustion and Energy Systems area seeks to focus on technologies for efficient energy conversion, storage and utilization, which aim to meet the urgent challenge of a safe, reliable and sustainable energy supply in the face of ever-growing demand and increasing geo-political uncertainty. Overall, our research spans the following technical areas: energy harvesting and storage, battery technology, thermal management of portable energy sources, energy storage materials, computational material science, electrochemical energy conversion and chemically reacting systems, combustion of fossil fuels, ignition and flame stabilization, and CFD of reactive flows. Our research on these subjects involves creative synthesis, sustainable technologies and engineering solution.
