Mohamed Hayek’s experience has focused on modeling single and multiphase flow and transport processes for a variety of applications, including safety assessment of waste sites, reactive transport, CO2 sequestration, contaminant transport, heat/mass transfer, and flow processes in both saturated and unsaturated regimes. He has been involved in several projects related to the framework of radioactive waste disposal programs for clients in Switzerland and France. He has modeled 3D radionuclide release from low-/intermediate-level waste (L/ILW) and high-level waste (HLW) repository sites under multiphase conditions (water/gas) using in-house and externally developed numerical codes. Mohamed developed an efficient mathematical method that has been implemented to model radionuclide release from a repository into the surrounding continuum and fractured formations. He also developed efficient numerical multiscale algorithms for progressive parameterization to estimate hydraulic parameters for both saturated and unsaturated regimes in single and dual porosity media. He has also developed efficient analytical models for flow in the unsaturated zone with applications to infiltration and evaporation process, reactive transport with investigations of clogging at concrete-clay interfaces in diffusive transport regime, two-phase flow in the framework of CO2 storage in deep geological formations, single-phase gas flow, and contaminant transport with investigations of sorption effects. Mohammed has authored more than 20 papers in international peer-reviewed journals and conference proceedings.
