Research Area：Energy and environmental engineering
Green Engineering, Clean Energy and Sustainability: Green engineering is the design, commercialization and use of processes and products, which are feasible and economical while minimizing impacts on ecosystems over the full life-cycle. In contrary to traditional engineering approaches in which both technical and economical aspects of a technology are the focal point, green engineering extends our research and development beyond the manufacturing of the material and product to include the ecological impacts of a process/product or a technology on the renewability and sustainability of the raw materials, the toxicity and health risks during the product use, and the recycleability and degradability at the end of the product use. We have been developing environmental systems analysis and life cycle analysis tools to model and evaluate biomass energy systems, as well as integrated impacts assessment of combustion and biomass gasification processes. We also work on the development of nano electro-catalyst particles for applications in PEM fuel cells. Both clean energy and green engineering will be key areas of my research and teaching in the near future.
Multiphase Reactors: Fluidized bed reactors have been widely used in industrial processes for conducting both catalytic and non-catalytic reactions, fuel combustion, particulate drying, powder coating and granulation, electrolysis etc. My current research is focused on hydrodynamics, flow patterns and flow regimes, heat transfer, mass transfer, reactor performance testing, modeling and simulation, scaling and scale-up,and novel reactors for catalytic NOx reduction.
