Dr. Hooman Tafreshi is a faculty member in the Mechanical and Aerospace Engineering Department at NC State University. He also serves as the Associate Director for Research at the Nonwovens Institute. Prior to joining NC State University, Dr. Tafreshi was with the Mechanical and Nuclear Engineering Department at Virginia Commonwealth University from 2007 to 2020, where he worked as assistant, associate, and Qimonda full professor. Dr. Tafreshi’s research is in the field of thermo-fluids sciences at its interface with material science. His particular research focus is on multiphase fluids and particle/droplet transport through fibrous materials with applications in filtration and separation sciences.  This also includes interfacial phenomena and droplet–surface interactions for self-cleaning and drag reduction applications. Dr. Tafreshi is an active member of the American Filtration and Separation (AFS) Society and also serves on the editorial board of Separation and Purification Technology journal. More detailed information about Dr. Tafreshi’s past and current research activities can be found on his Porous Media and Multiphase Flow (PMMF) Laboratory website (https://www.mae.ncsu.edu/pmmf/).



Research Description

Dr. Tafreshi's Porous Media and Multiphase Flow (PMMF) Laboratory conducts computational and experimental research in the field of multiphase fluid mechanics and heat transfer. Of particular interest is understanding the interactions between multiphase fluids/droplets and fibrous materials of heterogenous wettabilities. Such materials are used as superhydrophobic coatings (self-cleaning and drag reduction applications), in fluid absorbing product , and in droplet/particle separation (coalescence filtration, desalination membranes, or aerosol filters) among many other applications. Research activities of the PMMF laboratory also include structural modeling of nonwoven fibrous materials like those produced via electrospinning. To date, the PMMF laboratory has published more than 130 peer-reviewed journal articles in the above and other areas of thermo-fluid sciences, including liquid jets and two-phase nozzle flows. More detailed information about the past and current research activities of the PMMF laboratory can be found on the lab website (https://www.mae.ncsu.edu/pmmf/).
