Our group is interested in applying CFD to microscale gas flows

 

  • Experimental work at the Auburn University Center for Microfibrous Materials Manufacturing has shown significant increases in chemical reactivity using microfibrous materials
  • Our goal is to apply CFD to provide insight into the mechanisms of this increased reactivity
  • We would ultimately like to use CFD to design new materials which further enhance chemical reactivity
  • This effort is funded by the U.S. Army Tank and Automotive Command (TACOM)
  • Collaborators: Dr. Bruce Tatarchuk of the Chemical Engineering Department at Auburn University
