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 ...
Performance analysis of various machine learning algorithms for CO2 leak prediction and characterization in geo-sequestration injection wells
(
Elsevier
, 2024 , Article)
The effective detection and prevention of CO2 leakage in active injection wells are paramount for safe carbon capture and storage (CCS) initiatives. This study assesses five fundamental machine learning algorithms, namely, ...
Single and multiphase flow leak detection in onshore/offshore pipelines and subsurface sequestration sites: An overview
(
Elsevier
, 2024 , Article)
Leaks may occur in existing pipelines, even when designed with quality construction and appropriate regulations. The economic impact of oil spills and natural gas dispersion from leaks can be huge. Failure to detect pipeline ...
Thermoeconomic Analysis of a Solar-Assisted Industrial Process Heating System
(
Wiley-Hindawi
, 2024 , Article)
Thermal energy in the industrial sector for process heating applications in the range of 50 to 250°C consumes about 35% of the global fossil fuel. Cascaded solar thermal systems are promising solutions to meet clean and ...
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 ...
Performance investigation of solar photovoltaic panels using mist nozzles cooling system
(
Taylor and Francis Ltd.
, 2024 , Article)
Solar PV has a disadvantage over its many advantages that its electrical efficiency falls due to rise in surface/operating temperature of solar PV cells. Therefore, it is necessary to find a way to mitigate the efficiency ...
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 ...
