SUTTERBY NANOFLUID FLOW WITH MICROORGANISMS AROUND A CURVED EXPANDING SURFACE THROUGH A POROUS MEDIUM: THERMAL DIFFUSION AND DIFFUSION THERMO IMPACTS

This study anticipates examining a slip bioconvective movement of a non -Newtonian Sutterby nanofluid (SF) layer with motile microorganisms, where the fluid layer flows over a curved stretching surface. The movement is taken across a permeable medium under the influence of thermal diffusion, diffusion thermo, an unchanged vertical magnetic field (MF), joule heating, thermal radiation, and chemical reactions. The mathematical construction comprises momentum, energy, nanoparticles volume fraction, and microorganism concentration equations along with linear slip velocity and applicable boundary conditions (BCs). The motivation of the problem concerns recent progress in curved electronics and microchip technology, which made a growing development of the remarkable weaknesses of traditional planar electronics, which concerns the importance of the current work. Furthermore, the implication of this work emerges from the participation of microorganisms in the flow over a curved surface and shares with the temperature, velocity, and nanoparticle system of equations. This prototype is widely applicable in some manufacturing and engineering mechanisms like conduits, sports balls, combustion, inflated broadcast, and flow -structure contact between hydrodynamics and aerodynamics. The configuration of nonlinear partial differential equations (PDEs) is converted into ordinary differential equations (ODEs) by consuming suitable similarity transformations. The resulting equations are numerically analyzed via the fourth -order Runge-Kutta (RK-4) in concurrence with the shooting technique. The graphical construction of the targeted distributions is analyzed to recognize the effects of the relevant material coefficients. As key outcomes, it is noted that the greater the curvature of the surface, the greater the temperature, velocity, microorganisms, and nanoparticle distributions. Correspondingly, the Soret and Dufour impacts are found to be the improvement coefficients of the heat and dampness of both nanoparticle and microorganism condensation. Additionally, heat transmission develops with almost all relevant parameters, which is a noteworthy finding that can benefit potential applications.
