Professor Goodarz Ahmadi has developed a model for analyzing transport, dispersion, deposition and detachment processes of elongated fibers and particles of different sizes and shapes in turbulent flows. He and his group collaborated with Dr. Fagung Fan and Dr. Santokh Badesha of Xerox Corporation on this project. This model is especially useful because existing information is almost exclusively limited to spherical particles. Another joint project with Xerox has been the study of the effect of electrostatics on adhesion and removal of charged, bumpy toner-like particles. In related work, Dr. Ahmadi and his team analyzed the deposition of nano-particles and flexible fibers in turbulent duct flows.
