Research: 

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
