(American Institute of Physics, 2018-11-08)This study presents a simulation based optimization study of a multi-tube trapezoidal cavity receiver of a Linear Fresnel Collector plant in Pretoria, South Africa. A comprehensive optimization study - an optical, thermal ...
-
(Elsevier, 2023-11)Informative frequency band identification methods are used to automatically design bandpass filters to enhance fault signatures in vibration measurements. Blind and targeted features can be used to guide the frequency band ...
-
(MDPI, 2021-06-28)Response reconstruction is used to obtain accurate replication of vehicle structural responses of field recorded measurements in a laboratory environment, a crucial step in the process of Accelerated Destructive Testing ...
-
(MDPI, 2021-07)In this study, the convective mode heat transfer phenomena of bi-phase elasticoviscous (non-Newtonian) nanofluid is quantified by forcefully flowing it through a specially designed microchannel test section. The test ...
-
(MDPI, 2021-10-18)In this study, the efficacy of loading graphene oxide and copper oxide nanoparticles into ethylene glycol-water on viscosity was assessed by applying two numerical techniques. The first technique employed the response ...
-
(Hindawi, 2022-10-07)In this research, the CRDI engine characteristics were analyzed with the aid of exhaust gas recirculation rate (EGR) adoption fueled with ethanol blends. The test fuels were the various blends with ethanol, such as (10% ...
-
(Springer, 2012)The study evaluated bearing damage detection using SVAN 958 and laser. Accelerometers attached to SVAN 958 were used to measure the radial accelerations from the bearing housing. The laser which is an optical device was ...
-
(MDPI, 2022-10-24)This study proposes a decentralized hybrid energy system consisting of solar photovoltaics (PV) and wind turbines (WT) connected with the local power grid for a small Najran, Saudi Arabia community. The goal is to provide ...
-
(American Institute of Physics, 2020-12)CSP receivers are designed to permit higher outlet temperatures in order to enable higher theoretical efficiencies of the associated thermodynamic cycles. For pressurized air receivers, it is attempted to increase the ...
-
(American Institute of Physics, 2019-07-26)A new central receiver concept is being developed that attempts to trap solar rays and limit the re-radiation view factor. It has an array of hexagonal pyramid-like structures that form the absorbing surface facing the ...
-
(EDP Sciences, 2019-11)Phase change material (PCM) based Thermal Energy Storage (TES) system is a proven technology to store/release a large amount of energy as latent heat during the phase transition process. In spite of the advantages, a major ...
-
(Institute of Electrical Engineers of Japan, 2019)The development of high-performance mechatronic systems as well as the strong demand for environment-acceptable and safe intelligent technologies have had a profound impact on vehicle engineering. This impact has resulted ...
-
(King Saud University Press, 2019-04)This study assessed hazardous emissions from transesterified Palm Kernel Oil-based (PKO-based) biodiesel blends in a Compression Ignition Engine (CIE). Automotive Gas Oil (AGO) was blended with the PKO-methyl esters in ...
-
(Elsevier, 2023-11)Ceria-based H2O/CO2-splitting solar-driven thermochemical cycle produces hydrogen or syngas. Thermal optimization of solar thermochemical reactor (STCR) improves the solar-to-fuel conversion efficiency. This research ...
-
(MDPI, 2022-01-26)Over the last decade, the total primary energy consumption has increased from479 1015 BTU in 2010 to 528 1015 BTU in 2020. To address this ever-increasing energy demand, as well as prevent environmental pollution, ...
-
(European Geosciences Union, 2019-12-10)Over the last decade, advanced statistical inference and machine learning have been used to fill the gaps in sparse surface ocean CO2 measurements (Rödenbeck et al., 2015). The estimates from these methods have been ...
-
(Southern African Institute of Mining and Metallurgy, 2014-06)This investigation compares the results from an experimental and numerical study of air flow in a scaled-down underground coal mine model. This was done in order to determine if numerical analysis can be relied upon ...
