Dr Sassi is full professor of mechanical and materials engineering with over 25 years of multi-disciplinary progressive experience in Academia and Industry with very good expertise in academic program development, management, and assessment. In research he is an internationally known expert in thermo-fluids, combustion, air pollution control, carbon capture and sequestration, optical and spectroscopic diagnostics and analysis methods, computational fluid dynamics (CFD) with chemical kinetics simulation, and technology development for clean energy and environmental protection applications in general. Lately he has been very much involved and funded for Digital Rock Physics (DRP) and Enhanced Oil Recovery (EOR). He has a worldwide experience in USA, Europe, and Middle East North Africa (MENA) region.

Dr Sassi received his BSc in mechanical engineering from The University of Rochester, New York, and both his MSc and PhD from The University of California at Berkeley in Mechanical engineering with specialization in combustion and thermal sciences. Then during his work in France, he received a “Habilitation a Diriger des Recherches” in 1993 from Universite d’Orleans, France.

Aside from his teaching and research activity, Dr Sassi served as Department Head, Dean of Academic Programs both in Tunisia, in addition to Accreditation Lead, Doctoral Program Coordinator, and Interim-Dean of Faculty at Masdar Institute

  • MEG612: Multiphase flow in sub-surface porous media

Research Projects

  • CO2 Capture and Sub-surface Storage: Numerical and experimental studies of CO2 post- combustion capture, coupling between geomechanical, chemical, and transport processes during CO2 injection and storage in sub-surface porous media.
  • Experimental and Digital Rock Physics: Mechanical properties and multiphase flow properties from nanotomography to whole core scale analysis: Digital Rock Physics (DRP) is the novel and future reservoir engineering simulation tool. The approach is to use an ascending scale of integration of experimental and numerical modeling techniques. Nano, micro, and macro scale tomography is used to extract the complex pore scale and solid matrix network to be used within flow and mechanics simulators for the correct prediction of average macroscopic properties (porosity, permeability, formation factor, capillary pressure, relative permeability, elastic and shear moduli, and geomechanical/flow interactions) of carbonate rocks using pore scale and average model based solutions of the governing flow and elasticity equations for the prevailing geomechanical and multiphase flow phenomena and properties within the core sample.
  • Geomechanics Assessment of CO2 Injection Enhanced Oil Recovery (EOR) Pilot: Experimental and Numerical Simulation: Wellbore stability and Caprock Integrity through experimental characterization and numerical simulation studies of the interacting phenomena of geomechanics, multiphase flow, and geochemistry.
  • Experimental and Computational Investigation of the Pressure Buildup due to Fines Deposition in Trickle-Bed Reactors: experimental and computational investigation of the inter-play between flow regimes and fines deposition in trickle bed reactors in pursuit of mitigation of the pressure buildup problem.
  • Microwave Induced Plasma process for hydrogen, sulphur, and carbon black production:Numerical simulation studies using chemical kinetics and CFD modelling for the optimization of the plasma process toward the best product yield, and UV-Visible emission spectroscopy, IR spectroscopy, and gas analysis experimental work for process characterization, data input and/or validation of the numerical simulations.
  • Experimental and Simulation Approach to Optimize Hydraulic Fracturing Design for Unconventional Reservoirs: Experimental investigation of hydraulic fracturing in a tri-axial stress apparatus under reservoir conditions, fracture mapping characterization by ultra-sonic wave detection, and numerical simulation predictions.
  • Impact of Pore-scale Wettability Changes on Three-phase Relative Permeability Characterization in Carbonate Reservoirs: Building a 3D pore scale rock model from micro-CT images and experimental and numerical study of three-phase relative permeability.
  • SMART particle sensors for refinery catalytic bed reactors: Development and validation of micro-chip sensors to be loaded with the catalyst bed to measure temporal and spatial distribution of wettability, temperature and pressure in the catalytic bed reactor
