Airflow assessment in a naturally ventilated greenhouse equipped with wind towers: numerical simulation and wind tunnel experiments
( Elsevier Ltd , 2019 , Article)In this study, the air change rate and airflow distribution inside a greenhouse equipped with wind towers were analyzed using Computational Fluid Dynamics (CFD) simulations, considering different wind speeds (1–5 m/s) and ... -
Comparison of 1D and 3D heat and mass transfer models of a counter flow dew point evaporative cooling system: Numerical and experimental studyÉtude comparative numérique et expérimentale de modèles de transfert de chaleur et de masse 1D et 3D d’un système de refroidissement évaporatif à point de rosée à contre-courant
( Elsevier Ltd , 2019 , Article)In this study, the performance of a counter flow dew point evaporative cooling system has been examined, numerically and experimentally. A one-dimensional (1D) model of the heat and mass transfer in the cooling system is ... -
Contribution of Shell Eco-Marathon engineering design experience to soft skills development: A qualitative analysis in the Asian context
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference Paper)Recent studies emphasize the needs of a wider set of skills engineers require than ever thought. Engineering curricula have been frequently criticized. Engineering design experience is one remedial way of heavy theory ... -
Design of Qatar University's first solar car for Shell Eco-marathon competition
( IEEE , 2012 , Conference Paper)Research and development in the area of renewable energy is growing fast, supported by the increasing awareness about sustainability, environment and limitation of conventional sources of energy. Interestingly, oil and gas ... -
Evaluation of a novel greenhouse design for reduced cooling loads during the hot season in subtropical regions
( Elsevier Ltd , 2019 , Article)Greenhouses provide an optimized growth environment for plants. However, providing this environment is energy intensive. In subtropical regions, most of this energy is to cater for the required cooling. The cooling demand ... -

( IEEE , 2013 , Conference Paper)The demand for qualified national engineers is high in Qatar; Currently, a wide gap in supply exists. Consequently, urgent and proactive interventions at K-12 level to promote engineering profession to school students are ... -
Numerical and wind tunnel investigation of Hot Air Recirculation across Liquefied Natural Gas Air Cooled Heat Exchangers
( Elsevier B.V. , 2018 , Article)Air Cooled Heat Exchangers (ACHE)s are used for heat rejection in Liquefied Natural Gas (LNG) plants. Their thermal performance decreases under elevated ambient temperatures and windy conditions as exhaust air recirculates ... -
Performance evaluation of a near-surface earth-to-air heat exchanger with short-grass ground cover: an experimental study
( Elsevier Ltd , 2019 , Article)Given the negative environmental impact and high energy consumption of conventional air conditioning systems, the use of passive cooling systems has become particularly important. An earth-to-air heat exchanger, which ... -
Regression models for performance prediction of counter flow dew point evaporative cooling systems
( Elsevier Ltd , 2019 , Article)Practitioners take more interest in the output conditions of cooling systems than the details of the processes. In this study, regression models are developed that relate input parameters, including operational and geometrical ... -
Robustness analysis of the FFT-based segmentation, feature selection and machine fault identification algorithm
( British Institute of Non-Destructive Testing , 2019 , Article)This paper aims to experimentally investigate the robustness of a recently developed fast Fourier transform (FFT)-based segmentation, feature selection and fault identification algorithm for the development of practical ... -
Utilizing international design competitions for enhancing 21st century engineering skills: The experience of shell Eco-Marathon
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)Nurturing design skills in students is in the heart of all engineering curricula. While academic courses and capstone activities inject the design process in students, involvement in practical design activities is believed ...
