A significance of micro-motile organism's flow of nanofluid for heat transportation with thermal radiations

Abstract

The ability of nanofluids to improve heat transmission in thermal systems is well established. This work investigates the three-dimensional theoretical behavior of Darcy-Forchheimer nanofluids in tilted magnetohydrodynamics. In this study, the Soret effect, micro-motile organisms, thermophoresis, and heat radiation are also considered. The finite element method is used to solve the challenging mathematical model. Using graphs and tables, patterns may be seen in the velocity profiles, temperature distributions, concentrations of micro- and nano-motile organisms, and nanoparticle concentrations. The governing equations for mass, concentration, momentum, and motile microbes are derived using partial derivatives. These equations are then transformed into dimensionless ordinary differential equations utilizing appropriate similarity transformations. Permeability and viscosity have an impact on the properties of fluid flow. According to the results, improved thermophoresis and Brownian motion parameters raise the temperature profiles. In keeping with other studies, more inclined magnetohydrodynamics also accelerate heat transfer rates. The mass transfer rate at Fr=0.8 is 32.67% and 33.99% for Fr=1.4. Thus, mass transfer increased 1.32%. The novelties of the current work are: the Buongiorno nanofluid model is utilized for 3D geometry, inclined MHD and motile microorganisms are considered for rotating nanofluid flow, effects of slip and non-slip boundary conditions are compared, and the finite element technique is used to solve the developed problem.
