Computational Simulation Of Organic Rankine Cycle Retrofitted To Petroleum Well
( Hamad bin Khalifa University Press (HBKU Press) , 2014 , Conference Paper)Geothermal refers to existing heat energy in deep rock and sedimentary basins. Unlike other types of renewable energy resources, geothermal energy provides a stable source of energy as it can be exploited regardless of ... -
Digital Twin for Power Plants, Energy Savings and other Complex Engineering Systems
( Qatar University Press , 2021 , Poster)Digital Twin (DT) is a digital representation of a machine, service, or production system that consists of models, information, and data used to characterize properties, conditions, and behavior of the system. Renewable ... -
Energy conversion of heat from abandoned oil wells to mechanical refrigeration - Transient analysis and optimization
( Elsevier , 2012 , Article)This study investigates the potential of using the geothermal energy from abandoned oils in a novel three-loop system; geothermal, power and cooling loops to produce cooling effect. The geothermal loop drives the power and ... -
Experimental Investigation of Innovative Thermal Mechanical Refrigeration System
( Qatar University Press , 2021 , Poster)The current electrical refrigeration and air condition systems are considered as one of the major sources for ozone depletion and global warming problems. Furthermore, they consume a large percentage of the worldwide gross ... -
Ground response to global warming
( Springer Verlag , 2016 , Article)Owing to the awareness of the impact of global warming, there has been a growing interest in studying the relationship between the climatic changes and human activities. An increased global mean air temperature leads to ... -
Modified-thermal borehole shear test device and testing procedure to investigate the soil-structure interaction of energy piles
( ASTM International , 2017 , Article)The intermittent operation of heat pumps connected to energy piles causes cyclic variation of temperature in the pile and surrounding soil, affecting the soil-pile interaction in ways that have not been fully investigated ... -
Novel solar driven cooling system integrated with solar still system
( Qatar University Press , 2020 , Poster)Novel integrated solar cooling and solar distillation system is introduced to meet the high cooling and fresh water demands in hot and arid regions such as Qatar. The system is composed of a solar-driven ejector cooling ... -
Optimization of energy pile conductance using finite element and fractional factorial design of experiment
( Springer Verlag , 2019 , Book chapter)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 ... -
Retrofitting measures for reducing buildings cooling requirements in cooling-dominated environment: Residential house
( Elsevier Ltd , 2016 , Article)Air conditioning systems in hot and developing countries are the major energy consumers. Unfortunately, Arabian Peninsula countries still rely completely on fossil fuel. Therefore, there are compelling reasons to investigate ... -
Solar Energy For More Eco-friendly Mosque In Qatar
( 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 ... -
Spectral method solutions of a variable aspect ratio duct flow in a uniform transverse magnetic field with two different thermal boundary conditions
( 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
( 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 ... -
Uniform fractional factorial design tables for energy piles with maximum thermal conductance
( 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 ...
