This work provides a brief comparative analysis of the influence of heat creation on micropolar blood-based unsteady magnetised hybrid nanofluid flow over a curved surface. The Powell–Eyring fluid model was applied for modelling purposes, and this work accounted for the impacts of both viscous dissipation and Joule heating. By investigating the behaviours of Ag and TiO2 nanoparticles dispersed in blood, we aimed to understand the intricate phenomenon of hybridisation. A mathematical framework was created in accordance with the fundamental flow assumptions to build the model. Then, the model was made dimensionless using similarity transformations. The problem of a dimensionless system was then effectively addressed using the homotopy analysis technique. A cylindrical surface was used to calculate the flow quantities, and the outcomes were visualised using graphs and tables. Additionally, a study was conducted to evaluate skin friction and heat transfer in relation to blood flow dynamics; heat transmission was enhanced to raise the Biot number values. According to the findings of this study, increasing the values of the unstable parameters results in increase of the blood velocity profile.

This study investigates the various uses of density of motile microorganisms in the context of the flow of a binary base fluid with double diffusion past a vertical surface. The research aims to comprehend the interactions between motile microorganisms and the fluid dynamics, as well as the heat and mass transport mechanisms in this system. The analysis involves mathematically constructing the governing equations, transforming them into dimensionless nonlinear ordinary differential equations using similarity transformations, and numerically solving them using the MATLAB bvp4c solver. An analysis of the influence of several parameters on the profiles of velocity, temperature, concentration, nanoparticle concentration, and density of motile microorganisms is conducted using graphical representation. The findings demonstrate that boosting the thermophoresis parameter intensifies the temperature profile. In addition, an increase in the nanofluid Schmidt number results in a larger concentration of nanoparticles, whereas a higher bioconvection Lewis number reduces the density of the motile microorganism profile. These findings may find use in biomedical engineering as well as industrial processes that include enhancing the efficiency of mass transfer and bioconvection. Numeric simulation prophesies 99.9% for both shear stress and heat transfer rate intensification for Prandtl values are noticed.

This work explores the heat transfer properties and mathematical modeling of blood‐based hybrid nanofluid flow on a moving extensible surface in magnetohydrodynamic (MHD) flow. For the first time, this model is treated semi numerical with the influence of viscous dissipation. Blood, a complex biological fluid, is added to the nanoparticles aluminum oxide and copper as a base fluid for the formation of hybrid nanofluid. We formulate the governing partial differential equations assuming laminar, incompressible, and steady‐state flow. Applying the appropriate similarity transformation, a nonlinear system of ODEs is obtained from the recommended system of PDEs. Semi numerical simulations are utilized to analyze the effects of the flow and heat transfer characteristics of the including Eckert number, thermal radiation, magnetic field, couple stress parameter, and volume fraction of nanoparticles. The findings show that the magnetic factor, thermal radiation, and Eckert number significantly increase the rates of heat transfer, furthermore, the velocity field of hybrid nanofluid is decreasing with the increasing of couple stress, magnetic field, and nanoparticles volume friction, while skin friction is increasing with the increasing of couple stress, magnetic field, and nanoparticles volume friction. This work opens up new possibilities for optimizing heat transfer processes in biomedical applications involving blood flow by shedding light on the intricate interactions between surface stretching, hybrid nanofluid properties, and magnetic field effects.
