Dr. Ahmadi is currently working on projects for developing a new technique for modeling pollutant transport, dispersion and turbulent flows of dense and dilute, solid-gas or liquid mixtures with application to coal transport and processing, spray formation, and hot-gas filtration. Other projects are to analyze aerosol particles transport, deposition and removal in turbulent flows with application to micro-contamination control in microelectronic, xerographic and glass industries. Dr. Ahmadi has also been involved in developing schemes for active and passive vibration control of space structures during the lift off and in orbit, in addition to separation control of flapped airfoils, active control of turbulence flows, as well as subsurface flows. A related project is the base isolation of buildings in seismic regions for their protection against earthquakes.
Current research interests include: Evaluation of particle transport and deposition in microelectronic manufacturing and xerographic environment; in a related project, removal and re-suspension of particles and elongated fibers from smooth and rough surfaces in turbulent air flows are being studied; a major effort is also underway to quantify particle transport and deposition processes in coal energy systems, this project also includes developing physically sound models for dense and dilute two-phase and granular (particulate) flows; in a related project, the formation of fuel spray for application in racket engines is being studied; effective techniques for vibration control of various structures are being developed; in an earlier project, passive control of structures under earthquake excitations was studied, and new frictional systems for damping the structural vibrations was developed; in a related project, vibration control of aero space structures, including Space Shuttle during lift-off and on orbit, as well as avionic equipment, are being studied.
Professor Ahmadi has authored more than 600 papers in journals, in addition to three books and more 1100 papers in national and international conference proceedings. He has also given more than 160 keynote lectures and invited seminars worldwide. He is on the editorial advisory board of thirteen technical journals and is a fellow of ASME, ISME and ISCE. He was also a Senior Research Associate at National Energy Technology Laboratory (NETL). More information can be found on his research Web site.
