Soil-concrete interface properties subjected to temperature changes and cycles using direct shear tests
Xiao, Suguang; Suleiman, Muhannad T.; Elzeiny, Rehab; Xie, Huan; Al-Khawaja, Mohammed ( American Society of Civil Engineers Library (ASCE Library) , 2017 , Conference Paper)Geothermal foundations (energy piles) combine the structural function of deep foundations with the ground source heat exchangers to transfer geothermal energy to superstructures. The intermittent operation of the geothermal ... -
Solar Energy For More Eco-friendly Mosque In Qatar
Kharseh, Mohamad; Al-Khawaja, Mohammed; Abdu Ghani, Saud ( Hamad bin Khalifa University Press (HBKU Press) , 2014 , Conference Paper)There is mounting evidence that the global warming and, consequently, the climate changes are anthropogenic and attributed to fossil fuel consumption. Therefore, it is mandatory to find alternative solutions that can replace ... -

Al-Khawaja, M.; Al-Khawaja, Mohammed; Selmi, Mohamed ( Elsevier , 2020 , Article)© 2020 The Author(s) A laminar electrically-conducting flow inside an electrically-insulated rectangular duct in a uniform transverse magnetic field with both uniform surface temperature and uniform heat flux boundary ... -
Subcritical and Supercritical Operation of Innovative Thermal Mechanical Refrigeration System
Sleiti, Ahmad; Al-Ammari, Wahib; Al-Khawaja, Mohammed; Glushenkov, Maxim; Kronberg, Alexander ( Qatar University Press , 2020 , Poster)Around 17% of the global generated energy is consumed for residential, commercial, and transportation refrigeration. The current cooling technologies utilize refrigerants with high Ozone Depletion and Global Warming ... -
Supercritical Carbon Dioxide Power Cycle Integrated with Solar Power Tower and Oxy-Combustor
Sleiti, Ahmad K.; Al-Ammari, Wahib A.; Gamil, Ahmed I.; Al-Khawaja, Mohammed (2021 , Conference Paper)Power cycle that integrates solar power tower (SPT) system with direct oxy-combustion (DOC) supercritical CO2 cycle is proposed and investigated. In the SPT/DOC-sCO2 cycle (Cyc 3), the SPT works as preheater for the DOC/sCO2 ... -
Uniform fractional factorial design tables for energy piles with maximum thermal conductance
Ahmed, Khaled; Al-Khawaja, Mohammed; Suleiman, Muhannad ( WITPress , 2017 , Conference Paper)Energy Piles are the heat exchangers of Ground Source Heat Pumps (GSHP) that transfer the buildings heat to the lower temperature shallow ground reducing the energy consumption in the cooling of buildings. These piles are ...
