Professor (Joint Appointment)

Chemical Engineering and Materials Science

Dr. Rangel is interested in heat transfer, fluid mechanics, spray combustion, two-phase flows, fluid instability and atomization.

Dr. Rangel's current research activities focus on metal solidification in materials processing, droplet spray vaporization and combustion, and fluid mechanics and heat transfer of small particles in suspension.

The overall goals of the first project are to develop models for droplet deposition on flat and uneven surfaces, and to investigate the stability of solid fronts. In the second project, Dr. Rangel is looking at droplet streams and interaction effects, radiation absorption, ignition of droplet clouds and vaporization of binary droplets. The third effort is aimed at analyzing particle motion in unsteady Stokes flows.

Dr. Rangel also is studying the dynamics of aerosols, liquid atomization, and filling liquid acquisition devices in microgravity environments

Dr. Elghobashi is interested in the direct numerical simulation of turbulent, chemically reacting and dispersed two-phase flows.

His research is aimed at understanding some of the fundamental properties of turbulence using the direct numerical simulation (DNS) method, a numerical representation of the exact, three-dimensional, time-dependent Navier-Stokes equations. While the larger, long-term goal of his work is to predict engineering flows in complex geometries (the flow over an airplane or the flow of air inside a combustor, for example), Dr. Elghobashi currently is looking at chemically-reacting and particle-laden turbulent flows in simple geometries.

Dr. Elghobashi's work can be used to improve the mathematical closure models employed in predicting turbulent flows in practical applications.
