Optimization of design and operation of solar assisted district cooling systems
(
Elsevier
, 2020 , Article)
The demand for air conditioning and cooling services is rapidly increasing worldwide. As cooling demand has high coincidence to occur in countries with high solar irradiation, the combination of solar thermal energy and ...
Finite Element Analysis of the Mechanism of Traumatic Aortic Rupture (TAR)
(
Hindawi Limited
, 2020 , Article)
As many as 80% of patients with TAR die on the spot while out of those reaching a hospital, 30% would die within 24 hours. Thus, it is essential to better understand and prevent this injury. The exact mechanics of TAR are ...
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 ...
Investigation of the Effect of the Force-Frequency on the Behaviour of a New Viscous Damper for Railway Applications
(
Qatar Univesrity Press
, 2020 , Conference Paper)
The primary purpose of this work is to experimentally investigate the damping
coefficient of a viscous damper, intended to be used in railway applications to reduce
noise emission. The viscous shock absorber used in this ...
The Investigation of an Efficient and Effective Proactive Pipeline Integrity System
(
Qatar Univesrity Press
, 2020 , Conference Paper)
In this paper, we propose the investigation of an efficient and effective proactive pipeline
integrity system that uses multi-sensors for monitoring and inspection of the pipeline.
Although the focus is on the pipeline, ...
Estimation and measurement of effective line mobility on a non-deterministic thin plate excited by a piezoelectric patch
(
EXTRICA
, 2020 , Article)
This paper derived the expression to estimate the effective line moment mobility of a non-deterministic thin plate under moment excitation by a piezoelectric patch actuator. The piezoelectric patch actuator is assumed to ...
Investigating the effect of the air inlet temperature on the combustion characteristics of a spark ignition engine fueled by biogas
(
Wiley-Blackwell
, 2020 , Article)
This work has conducted a numerical study using AVL-Boost engine simulation utilizing biogas (CH4 and CO2)–air mixtures in a SI engine model. The effect of varying the air manifold temperature from 25 to 50°C on the ...
Tools and Techniques for Food Security and Sustainability Related Assessments: A focus on the Data and Food Waste Management System
(
IEOM Society International
, 2020 , Conference Paper)
Achieving global food security requires addressing series of challenges, from food waste accumulation in the food
supply chain (FSC) to tackling the gender disparities and climate-related concerns to promote sustainable ...
Potential of geothermal energy for electricity generation in Qatar
(
Canadian Institute of Mining, Metallurgy and Petroleum
, 2013 , Conference Paper)
There is general acceptance that climate change, which is the most important challenge facing humanity, is anthropogenic and attributed to fossil fuel consumption. Therefore, improving the performance of our existing energy ...
On the aero acoustic and internal flows structure in a centrifugal compressor with hub side cavity operating at off design condition
(
Elsevier
, 2016 , Article)
This paper covers the characterization of the acoustic noise and the unsteady flow field of a high speed centrifugal compressor NASA CC3. In order to accurately predict the noise, all analyses are carried out through the ...
