Abandoned petroleum wells as sustainable sources of geothermal energy
Templeton, J.D.; Ghoreishi-Madiseh, S.A.; Hassani, F.; Al-Khawaja, M.J. ( Elsevier Ltd , 2014 , Article)A reliable heat transfer model was developed to determine the performance of a double pipe heat exchanger retrofitted to an abandoned petroleum well. The proposed model is compared against an analytical heat transfer model ... -
Axial pull-out response of a small-scale concrete pile subjected to cyclic thermal loading in sand
Elzeiny R.; Suleiman M.T.; Qamar M.A.; Xiao S.; Al-Khawaja M. ( American Society of Civil Engineers (ASCE) , 2018 , Conference Paper)Energy piles support structural loads and exchange heat with surrounding soils using closed-loop ground source heat pump (GSHP) systems. A GSHP connected to an energy pile operates in cycles where it functions for a period ... -
Cyclic loading effects on soil-energy pile interaction
Xiao, S.; Suleiman, M. T.; Elzeiny, R.; Al-Khawaja, M. J. ( CRC Press/Balkema , 2016 , Conference Paper)To reduce greenhouse gas emission from space heating and cooling, energy piles have been used in buildings as an alternative renewable energy source for approximate by two decades. However, the effects of cyclic thermal ... -
Effect of temperature and radial displacement cycles on soil?concrete interface properties using modified thermal borehole shear test
Xiao S.; Suleiman M.T.; Elzeiny R.; Naito C.; Neti S.; Al-Khawaja M.... more authors ... less authors ( American Society of Civil Engineers (ASCE) , 2018 , Article)Thermoactive geostructures (such as energy piles) are used for heating and cooling of buildings, which generate daily temperature changes and cycles in the geostructure and surrounding soil due to the intermittent operation ... -
Numerical study of magneto-fluid-mechanic combined free-and-forced convection heat transfer
Al-Khawaja, M. J.; Agarwal, R. K.; Gardner, R. A. ( Elsevier , 1998 , Article)Fully-developed, laminar, steady, free-and-forced convection heat transfer in an electrically-conducting fluid flowing in an electrically-insulated, horizontal, circular pipe (with its wall subjected to a uniform heat flux) ... -
Numerical Study Of Magneto-Fluid-Mechanics Forced Convection Pipe Flow
Al Khawaja, M. J.; Gardner, R. A.; Agarwal, R. ( Qatar University , 1994 , Article)The problem of fully developed, laminar, steady, forced convection heat transfer in an electrically conducting fluid flowing in an electrically insulated, horizontal, circular pipe (whose wall is subjected to a uniform ... -
Optimal utilization of geothermal heat from abandoned oil wells for power generation
Kharseh M.; Al-Khawaja M.; Hassani F. ( Elsevier Ltd , 2019 , Article)Unlike other types of renewable energy, geothermal resources represent a stable energy source because they can be exploited regardless of meteorological conditions. In geothermal systems, heat is exchanged between the ... -
Optimization of energy pile conductance using finite element and fractional factorial design of experiment
Ahmed K.; Al-Khawaja M.; Suleiman M. ( Institute of Physics Publishing , 2018 , Conference Paper)In Ground Source Heat Pumps (GSHP), Energy Piles pose as heat exchangers that transfer the heat from the buildings to the shallow ground lower temperature in order to decrease the energy consumption whilst cooling the ... -
Spectral method solutions of a variable aspect ratio duct flow in a uniform transverse magnetic field with two different thermal boundary conditions
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 ... -
Utilization of oil wells for electricity generation: Performance and economics
Kharseh, M.; Al-Khawaja, M.; Hassani, F. ( Elsevier Ltd , 2015 , Article)There is a general agreement that the climate change, which is the most important challenge facing humanity, is anthropogenic and attributed to fossil fuel consumption. Therefore, deploying more renewable energy resources ...
