• Simulation study and optimization of energy and environmental processes using Computational Fluid Dynamics – CFD
• The fluid flow and the transport phenomena (energy, radiation, mass transfer, chemical reactions etc) are described by a set of partial differential equations the Navier-Stokes equations. Computational Fluid Dynamic is a numerical technique for solving these equations. Computational Fluid Dynamic is a useful tool for the study of any process involving fluid flow and transport phenomena (heat, mass transfer, radiation etc).
