Research

Computational Fluid Mechanics
 

Overview

Primary research in computational fluid dynamics is a branch known as computational two-phase flow. Faculty are involved in developing and using numerical methods directed toward the simulation of flows during which phase change causes mass to be transferred across moving distorting phase interfaces.

Recently, faculty have also become interested in interface tracking including the effects of electrohydrodynamics.

Projects

Current projects in computational fluid mechanics are:

  • Simulation of deformable droplet migration due to electrocapillary forces.
  • Electrohydrodynamic improvement of boiling heat transfer
