My principal research interests lie in the field of modeling and implementing numerical models of multiphysics couplings in mechanics.
I am currently interested on the development of low computational cost Nanosecond Repetitively Pulsed (NRP) discharges models. These models enable to perform Direct Numerical Simulation (DNS) of plasma-assisted combustion, and help understanding the complex physics underlying thermal non-equilibrium reactive flows.

Plasma assisted combustion:
- Developed a low computational cost Nanosecond Repetitively Pulsed (NRP) discharges models for a better understanding of the complex physics underlying thermal non-equilibrium reactive flows in OpenFOAM.
Ionic wind:
- Developed a 1D simplified ionized layer model for a better understanding of the electric field response when alternative current (AC) is applied to a flame.
- Studied the effect of the phenomenological time scales to understand the behavior of the electric current.
- Developed a 2D axisymmetric simulation in OpenFOAM for a counterflow configuration when AC electric field is applied into flames.

Study of radiative transfer of Air thermal plasma: Influence of radiative properties in the simulation of a free-burning arc:
- Determined the thermo-physical properties under Local Thermodynamic Equilibrium of Air+Cu plasma: Composition, Thermodynamic properties, Transport coefficients.
- Calculated radiative properties using two different approximate methods (Net emission coefficient and Mean Absorption Coefficient).
- Optimized the approximate methods in order to procure more accurate prediction in the radiative transfer in Air+Cu plasma
- Developed a Magneto-Hydro-Dynamic model of a free-burning arc to see the impact of radiative properties on the arc temperature.

Development of a CFD-based Heat Exchanger Geometry optimization Framework:
- Reviewed previous published studies on heat exchanger optimization, in terms of geometries, applications, operational conditions, optimization methodologies and findings.
- Developed a modeling framework for heat exchanger numerical optimization, based on the coupling of ANSYS/Fluent Version 16.1 (CFD software) with modeFRONTIER 2014 (numerical optimization software) and MATLAB 2013 (for heat exchanger geometry parametrization).
- Applied the developed modeling environment to the optimization of unfinned tube bank and webbed tube bank for a range of solid wall thermal conductivities, composite polymers, and metallic alloys.
