Research topics

 

My research is concerned on Computational Fluid Dynamics with particular focus on heat transfer for various engineering problems arising  in confined / free media in cartesian /cylindrical coordinates systems such as plasma coating processes. The most interesting issue in my modelings is that I employ a new and powerful numerical tool, namely the Lattice Boltzmann Method (LBM) to solve flow & heat PDEs.


        Research topics include, but not limited to:

+ Problems of flows and heat transfer including Magneto-hydrodynamic MHD, Dynamics of unsteady flows, transition and symmetry breaking in Bridgman models, low-Prandtl number flows, porous media flows,

+ Heat transfer enhancement by nanofluids,

+ Drying processes /Pyrolysis / TEG systems (Peltier&Seebeck),
+ Thin solid films / Coatings / Thermal spraying processes / plasma jets dynamics,

+ Turbulence, Large Eddy Simulation (LES),

+ Taguchi Experimental Design  /Optimization,

+ Numerical simulation and modeling using Lattice Boltzmann method (LBM) & Finite Volumes (FVM), Fire Dynamics Simulator (FDS), Fluent and COMSOL multiphysics.
