Analysis of ferrite nanoparticles in the flow of ferromagnetic nanofluid
( Public Library of Science , 2018 , Article)Theoretical analysis has been carried out to establish the heat transport phenomenon of six different ferromagnetic MnZnFe2O4—C2H6O2 (manganese zinc ferrite-ethylene glycol), NiZnFe2O4—C2H6O2 (Nickel zinc ferrite-ethylene ... -
A computational model for suspensions of motile micro-organisms in the flow of ferrofluid
( Elsevier , 2020 , Article)The performance of friction drag, heat transfer rate, and mass transfer is illustrated the in boundary layer flow region via density of motile microorganisms. Magnetic dipole in presence of Curie temperature and density ... -
Hydrodynamics and ferrite nanoparticles in hybrid nanofluid
( Elsevier , 2020 , Article)The solids have higher heat transfer rate comparative to fluids, thus, in the present article, two different ferrite nano-particles are suspended in two different base fluids to demonstrates its impacts on the friction ... -
Effect of asymmetrical heat rise/fall on the film flow of magnetohydrodynamic hybrid ferrofluid
( Springer Nature , 2020 , Article)The movement of the ferrous nanoparticles is random in the base fluid, and it will be homogeneous under the enforced magnetic field. This phenomenon shows a significant impact on the energy transmission process. In view ... -
OpenFOAM for computational combustion dynamics
( Springer Nature , 2022 , Article)In computational fluid dynamics (CFD), the mathematical description of a physical phenomenon that involves fluid flow, combustion, and chemical reaction is combined with a numerical solution of the problem via the use of ... -
Algorithms for simultaneous block triangularization and block diagonalization of sets of matrices
( AIMS Press , 2023 , Article)In a recent paper, a new method was proposed to find the common invariant subspaces of a set of matrices. This paper investigates the more general problem of putting a set of matrices into block triangular or block-diagonal ... -
Zooplankton abundance and community structure driven by tidal currents in a Mediterranean coastal lagoon (Boughrara, Tunisia, SW Mediterranean Sea)
( Academic Press , 2021 , Article)Lagoons and coastal marine zones are very productive and useful ecosystems, but they are threatened by the effects of global change and anthropogenic pressures. These effects have a negative impact on the zooplankton, ... -
Unfolding jellyfish bloom dynamics along the mediterranean basin by transnational citizen science initiatives
( MDPI AG , 2021 , Article)Science is addressing global societal challenges, and due to limitations in research financing, scientists are turning to the public at large to jointly tackle specific environmental issues. Citizens are therefore increasingly ... -
Acute and chronic toxicity assessments of 17β-estradiol (E2) and 17α-ethinylestradiol (EE2) on the calanoid copepod Acartia clausi: Effects on survival, development, sex-ratio and reproduction
( Elsevier B.V. , 2022 , Article)Estrogens, such as the 17β-estradiol (E2) and the 17α-ethinylestradiol (EE2), have been regarded as a global threat to aquatic ecosystems due to their pseudo-persistence, their high estrogenic activity and their toxicity ... -
Contamination of planktonic food webs in the Mediterranean Sea: Setting the frame for the MERITE-HIPPOCAMPE oceanographic cruise (spring 2019)
( Elsevier Ltd , 2023 , Article)This paper looks at experiential feedback and the technical and scientific challenges tied to the MERITE-HIPPOCAMPE cruise that took place in the Mediterranean Sea in spring 2019. This cruise proposes an innovative approach ... -
MHD effects on nanofluid with energy and hydrothermal behavior between two collateral plates application of new semi analytical technique
( Vinca Inst Nuclear Sci , 2017 , Article)In this study, heat and mass transfer characteristic of unsteady nanofluid flow between parallel plates is investigated. The important effect of Brownian motion and thermophoresis has been included in the model of nanofluid. ... -
History of a disaster: A baseline assessment of the Wakashio oil spill on the coast of Mauritius, Indian Ocean
( Elsevier Ltd , 2022 , Article)Oil spills from tanker ships provide adverse and irreversible impacts of a pollutant over coastal and marine environments. Using Sentinel-1 and 2 satellite images, this baseline paper presents the detection, assessment, ... -
