Summary: This article presents a study on mixed convection in the presence of a magnetic field near an oblique stagnation point in micropolar nanofluid. Similarity transformations are used to convert the governing partial differential equations into non-linear ordinary differential equations, which are then solved using the modified Chebyshev collocation method. The accuracy of the method is demonstrated by comparing the numerical results with those obtained using the finite difference method. The study provides graphical results for velocity components, microrotation, temperature, and flow patterns, and calculates numerical values for various parameters such as the free parameter, skin friction, and Nusselt numbers. The findings reveal that the microrotation profiles are influenced by the stretching effect and the angle of strike, while the temperature of the micropolar nanofluid is affected by the magnetic parameter and micropolar coefficient. The temperature gradient of the nanofluid decreases with increasing values of the stretching parameter and the angle of strike.

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.
