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 ...
Combined heat and power system based on Solid Oxide Fuel Cells for low energy commercial buildings in Qatar
(
Elsevier
, 2021 , Article)
Commercial buildings in Qatar account for 19% of the total energy consumption in the country. To reduce this significant amount of energy, a Solid Oxide Fuel Cell Combined Heat and Power (SOFC CHP) system with natural gas ...
Heat transfer measurements of Polyalpha-Olefin- boron nitride nanofluids for thermal management and lubrication applications
(
Elsevier
, 2020 , Article)
In this paper, the first study is reported combining Polyalpha-Olefin (PAO) oil with hexagonal Boron Nitride (hBN) to produce new class of nanofluids for heat transfer and lubrication applications. The heat transfer ...
Dataset for measured viscosity of Polyalpha-Olefin- boron nitride nanofluids
(
Elsevier
, 2021 , Dataset)
Datasets of measured viscosity of Polyalpha-Olefin- boron nitride (PAO/hBN) nanofluids are reported. An AR-G2 rheometer (from TA Instruments) experimental setup is used for measuring the rheological property of PAO/hBN ...
Harvesting water from air using adsorption material - Prototype and experimental results
(
Elsevier
, 2021 , Article)
Drinking water resources have always been limited in the gulf region of the Middle East and other desert regions around the world. In attempt to provide viable supplement, a device that harvests clean drinking water from ...
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 ...
Isobaric Expansion Engines Powered by Low-Grade Heat-Working Fluid Performance and Selection Database for Power and Thermomechanical Refrigeration
(
Wiley-VCH Verlag
, 2020 , Article)
A database is developed for the most suitable working fluids for Worthington-type and Bush-type isobaric engines based on their performances for a wide range of heat source temperature, from 40 to 300 °C, and operating ...
Large-eddy simulation of the flow in Z-Shape duct
(
Cogent OA
, 2020 , Article)
A numerical study is conducted of the transient flow in a z-shape three-dimensional duct using large-eddy simulation (LES) with dynamic eddy viscosity subgrid-scale (SGS) model with a fully structured grid system. The ...
Targeted and suspect screening of contaminants in coastal water and sediment samples in Qatar
(
Elsevier B.V.
, 2021 , Article)
In recent years, high resolution mass spectrometry (HRMS) combined with separation techniques has allowed comprehensive analysis of contaminants of emerging concern (CECs) as well as their metabolites and transformation ...
Modified Quantum Particle Swarm Optimization For Selective Harmonic Elimination (SHE) in A Single-phase Multilevel Inverter
(
International Journal of Innovative
, 2021 , Article)
The Multilevel Inverter (MLI) uses Selective Harmonic Elimination (SHE) of the Pulse Width Modulation (PWM) approach to tackle the fundamental harmonics with the elimination of selected lower harmonics. The optimal switching ...
