Mohammad Vahabi is an assistant professor of mechanical engineering at Islamic Azad University, Central Tehran Branch. Vahabi holds BSc and PhD degrees in mechanical engineering from the University of Tehran and an MSc from Shiraz University. Vahabi’s research uses computational fluid dynamics, chiefly smoothed particle hydrodynamics (SPH), to simulate non-Newtonian flows: bubbles rising in viscoelastic and thixotropic liquids, droplet deformation under shear, dam-break flow and Rayleigh-Taylor instability. Earlier work modelled CO-oxidation microreactors for fuel cells. Vahabi has co-authored studies of nanofluid heat transfer and radiative cooling of photovoltaic panels.

Interested in hearing about: Collaborations on SPH and CFD simulation of viscoelastic and thixotropic fluids, bubbles, droplets and free-surface flows.
