Many real-world devices, such as heat exchangers, geothermal reservoirs, and cooling systems, utilize the concept of boundary layer flow across a cone geometry. The current study presents and analyses the mathematical formulation for the mixed convection flow of a hybrid nanofluid over a permeable stationary cone. The heat transfer analysis considers the effects of thermal radiation and convective

Analysis of radiative heat transfer on electro-osmotic magneto nanofluid flow through ciliary propulsion ZAMM (IF 2.3) Pub Date : 2024-01-17 Ali Imran, Muhammad Asif Zahoor Raja, Saeed Ehsan Awan, Muhammad Shoaib
A novel mathematical investigation is carried out to reveal the significance of thermal radiation on the dissipative magneto hydrodynamic electroosmotic ciliary propulsion of a Newtonian nanofluid (DMHECP-NNF) in an symmetric micro-channel by implementing the impact of an axial electrical as well as transverse magnetic fields. The ciliary transport model is explored by using conservation of mass and

Mathematical modelling of couple stress fluid flow around a semi-permeable sphere enclosing a solid core ZAMM (IF 2.3) Pub Date : 2024-01-17 Ramasamy Selvi, Osman Anwar Bég
The focus of this article is to study theoretically the steady-axisymmetric creeping flow dynamics of a couple stress fluid external to a semi-permeable sphere containing a solid core. This problem is motivated by emulsion hydrodynamics in chemical engineering where rheological behaviour often arises in addition to porous media effects. The non-Newtonian Stokes’ couple stress fluid model features couple

Pressure stabilization method for the 2D/3D time-dependent natural convection equations with salt concentration ZAMM (IF 2.3) Pub Date : 2024-01-17 Youlei Liang, Demin Liu
In this paper, the pressure stabilization method for the 2D/3D time-dependent natural convection equations with salt concentration (NCSC) is considered. The artificial pressure diffusion term is introduced to reduce the constraint of the incompressible condition. The first-order backward difference formula is adopted to approximate the temporal derivative terms, the diffusion terms in NCSC are treated
