Investigating the characteristics of a magnetorheological fluid damper through CFD modeling
(
Institute of Physics Publishing
, 2021 , Article)
Computational Fluid Dynamics (CFD) analysis is conducted on mono-tube vehicle MRF damper investigated experimentally in a previous study. In this study, the fluid of the type MRF-132DG was inserted inside a damper of a car ...
Data Interpretation Framework for Pile Thermal Integrity Testing
(
Qatar University Press
, 2023 , Conference Paper)
Given the inherent nature of how deep cast in-situ concrete foundations (piles and diaphragm walls) are constructed, evaluating their integrity is difficult. Several well-established methods for testing integrity have been ...
Fines effect on gas flow in sandy sediments using μCT and pore networks
(
Elsevier
, 2022 , Article)
Gas production from hydrate-bearing sediments requires methane dissociation, which induces two-phase gas flow, mobilizing fine clay particles from within saturated pores. Fines migration within sandy sediments results in ...
Shear behavior of green concrete beams reinforced with basalt FRP bars and stirrups
(
Elsevier
, 2021 , Article)
This study investigated the shear performance of large-scale green concrete (GC) beams reinforced with basalt fiber reinforced polymer (BFRP) bars and stirrups. The GC concept was employed in this study by partially ...
Estimating the Relative Crystallinity of Biodegradable Polylactic Acid and Polyglycolide Polymer Composites by Machine Learning Methodologies
(
MDPI
, 2022 , Article)
Biodegradable polymers have recently found significant applications in pharmaceutics processing and drug release/delivery. Composites based on poly (L-lactic acid) (PLLA) have been suggested to enhance the crystallization ...
Enhancement of Naphthalene Degradation by a Sequential Sulfate Injection Scenario in a (Semi)-Arid Coastal Soil: a Flow-Through Reactor Experiment
(
Springer
, 2020 , Article)
Engineered sulfate injection has been introduced as an effective technology to enhance the remediation of soil and groundwater contaminated by petroleum hydrocarbons. While some studies indicate that sulfate injection is ...
Parametric Optimization of RC Beams Strengthened with FRCM Using FE Modelling and Response Surface Methodology
(
Qatar University Press
, 2023 , Conference Paper)
This study focuses on the numerical and statistical analyses to predict the mid-span moment capacity of RC beams strengthened with fabric reinforcement cementitious mortar (FRCM) laminate. A finite element model (FEM) has ...
Energy harvesting from railway vibrations - A numerical study based on beam-on-elastic-foundation under quasi-static loading
(
National Technical University of Athens
, 2021 , Conference Paper)
The objective of this paper is to investigate energy harvesting of train-induced rail
vibrations and to provide a comparison between various feasible harvesting locations based on
the expected electrical power output. ...
Retention of Hydrophobic Colloids in Unsaturated Porous Media using Microfluidics
(
Qatar University Press
, 2023 , Conference Paper)
Water recharge wells can provide a solution for 3.5 billion people, living in regions suffering from water scarcity. Due to fines migration, freshwater wells that are used to recharge aquifers, often experience expedited ...
3D simulation models for developing digital twins of heritage structures: Challenges and strategies
(
Elsevier
, 2021 , Conference Paper)
Structural vulnerability assessment of heritage structures is a pivotal part of a risk mitigation strategy for preserving these valuable assets for the nations. For this purpose, developing digital twins has gained much ...
