Hydrothermal study on nano-bioconvective fluid flow over a vertical plate under the effect of magnetic field

Abstract

The surprising importance of nanoparticles and microorganisms in energy production, pharmaceuticals, and cooling applications has made us investigate them further. This study has produced encouraging results that could potentially be applied to enhance heat dissipation in large-scale technological processes. In this study, the vertical bioconvective flow of nanofluid-containing microorganisms was analyzed. Parameters Incorporated within the equations are magnetic field, thermal radiation, and viscous dissipation. Using similarity parameters, ODE (Ordinary Differential Equation) equations derived from partial derivative equations for continuity, momentum, energy, nanofluid concentration, and microorganisms’ concentration. Implementing similarity measures allows for transforming a set of partial differential equations into a regular differential pattern. Fifth-order Runge-Kutta was then utilized to solve the equations. The influence of the magnetic field on various profiles of velocity, temperature, nanofluid concentration, microorganism concentration, Nusselt number, and skin friction was studied for various values. The results show that when $\mathrm{\alpha }$ rises, and Ha remains the same, $F^{\prime }\left(\xi \right)$ and $\theta (\xi )$ fall, during $x(\xi )$ and $\varphi (\xi )$ grow. Furthermore, a significant result is that a thermophoresis parameter exerts a force on neighboring particles, which causes them to shift from a hot zone to a cool region, and the density of microorganisms inside a region rises as the thermophoresis parameter grows.
