( Qatar University Press , 2023 , Conference Paper)The Musaimeer Pump Station & Outfall Tunnel project (MPSO) was constructed as one of the longest Outfall tunnels in the World with a total length of 10.189m and at the same time being the longest undersea tunnel in the ... -
Turbuelence Modeling and Valication to Predict Velocity Profiles in Close-Coupled Five-Gore Elbows
(2021 , Dissertation)This research work aims to validate advanced turbulence modeling techniques used to predict complex flows in close-coupled five-gore elbows and similar complex geometries using data from 2016 ASHRAE RP-1682 (Study to ... -
Turbulence effects on the autoignition of DME in a turbulent co-flowing jet
( Elsevier , 2017 , Article)Dimethyl ether (DME) autoignition in turbulent co-flowing jets with preheated air is studied using the one-dimensional turbulence (ODT) model. We investigate the effects of molecular and turbulent transport on the autoignition ... -
Turbulence Modeling Using Z-F Model and RSM for Flow Analysis in Z-SHAPE Ducts
( Wiley , 2020 , Article)Turbulent flow in Z-shape duct configuration is investigated using Reynolds stress model (RSM) and ζ-f model and compared to experimental results. Both RSM and ζ-f models are based on steady-state RANS solutions. The focus ... -
Turbulence modeling using Z-F, RSM, LES and WMLES for flow analysis in Z-Shape ducts
( American Society of Mechanical Engineers (ASME) , 2020 , Conference Paper)Turbulent flow in Z-shape duct configuration is investigated and analyzed using Reynolds Stress Model (RSM), Large Eddy Simulation (LES), ζ-f Model, and Wall-Modeled Large Eddy Simulation (WMLES). The results are validated ... -
Turbulent Flames in Enclosed Combustion Chambers: Characteristics and Visualization - A Review
( American Society of Mechanical Engineers (ASME) , 2020 , Article)Remarkable progress has been achieved in measuring the flame propagation rate accurately under laminar conditions, which can be used to predict turbulent flame propagation rates using some correlations fitted to experimental ... -
