Summary: This study presents the numerical solution for the flow of non-Newtonian fluid induced by a stretching sheet in the region of oblique stagnation point under the influence of an externally applied uniform magnetic field orthogonal to the flow. The analysis is based on the assumption of a boundary layer and transforms the system of partial differential equations into ordinary differential equations using appropriate similarity transformations. The numerical results show that an increased magnetic field leads to a decrease in horizontal velocity and thinning of the boundary layer, which are in excellent agreement with existing results in the literature in limiting cases.

Summary: Physiological systems and biological applications in the past 15 years heavily rely on microscale and nanoscale fluxes. Microchannels have been used for diagnostic assays, cell adhesion and molecular transport studies, and mimicking circulatory system flow. MHD boundary flow has wide applications in engineering and technology, including power generation, polymer industry, flow meters, pumps, and filament spinning. This investigation focuses on the Magnetohydrodynamic (MHD) flow of Prandtl nanofluid, involving mixed convection, energy activation, microorganism, and chemical reaction. The study presents numerical outcomes and graphs on velocity profile, temperature, mass concentration, and microorganism density, considering various parameters like Prandtl fluid parameter, elastic fluid parameter, magnetic field, mixed convection parameter, activation energy, chemical reaction, Brownian motion, thermophoretic force, Prandtl number, and Schmidt number. The results show that the Prandtl fluid parameter and elastic fluid parameter enhance the velocity profile, while the Prandtl fluid parameter reduces the thermal rate with increasing concentration profile. Activation energy exhibits the opposite trend. The obtained numerical outcomes are compared with existing statistics and show good agreement in limiting cases.

Summary: This study investigates the Marangoni convection flow of Al2O3/water-based nanofluid over a stretching sheet in a porous medium with thermophoretic particle deposition (TPD) and Newtonian heating. The velocity of the nanofluid is influenced by the Marangoni number and porosity parameter, while the heat absorption/generation parameter improves thermal dispersion. The thermophoretic parameter affects the concentration and rate of mass transfer, and the heat source and heat sink parameters influence the rate of heat transfer. Nanofluid outperforms viscous fluid in all cases.
