  • اهتمامات البحث العلمي:

​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.

Jul 2019 – Present: Postdoctoral fellow (Thuwal)

​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.
Supervisor: Prof. Hong G. Im​

Nov 2015 – Mar 2019: PhD. in Plasma Physics and Mechanical Engineering | Research Engineer at Siemens / University Paul Sabatier (Toulouse)

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.
Supervisors: Yann Cressault, Philippe Teulet (LAPLACE) and Eric Durhone (Siemens).

Feb 2015 – Aug 2015: Research Assistant, The Petroleum Institute / ADNOC (Abu Dhabi)

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.
Supervisors : Valerie Eveloy, Peter Rodgers (The Petroleum Institute)


Jun 2014 – Sep 2014: Internship, General Electric (Grenoble)

Documentation and analysis of a database to optimize Turbines-Pumps characteristics:
  • Gathered in a database a large number of configurations tested for Turbines-Pumps.
  • Developed functions to find hydraulics characteristics related to experimental tests using Scilab software
  • Established correlations between the relevant parameters for all configurations retained.
Supervisors: Laetitia Balarac, Yann Laurant (General Electric)
