    Faculty: Engineering and Applied Science
    Field of Research: Renewable Energy

    A mechanical engineer with a Doctor of Philosophy of Applied Science (PhD), specializing in Renewable Energy systems, Sea Wave Energy Conversion System, Wind Energy, Hydrokinetic Energy, Power Generation, Thermofluid and Turbomachinery.

    Research and professional highlights
    • Accumulated over 10 years of expertise in Computational Fluid Dynamics (CFD) utilizing the ANSYS Fluent- ANSYS AQWA software suite, in addition to four years of experience in TRNSYS simulation tools.
    • Developed a novel technology and filed a patent for a hydrokinetic turbine designed to harness mechanical energy from river currents under the title of SSWT, which also serves a dual function as a wind turbine.
    • Demonstration of Smart Water Systems for Sustainable Cities: modeling and calculating water consumption and wastewater usage, integrating the capability to recycle wastewater within buildings, and developing various scenarios for water recycling within buildings to reduce water consumption and optimize costs. Utilized Multiphysics modeling and ANSYS-Fluent simulations to calculate water flow rates, network pressure and water velocity in the pipe.
    • Designed and built an innovative hydrogen generation system with an efficiency exceeding 94 per cent.
    • Developed a sea wave energy conversion system called Wave Hunter to convert the sea wave into mechanical energy.
    • Skilled in visualizing and post-processing numerical and experimental data from various engineering fields.
