Abstract

This article inspects the bioconvection flow of second-grade nanomaterial in a magnetic field upon a revolving stretching disk under the Darcy-Forchheimer theory. Radiated heat, heat generation/absorption and chemical reaction have been incorporated. Thermal and solutal convective conditions are assumed to compute heat and mass. The Buongiorno nanofluidic is assumed to simulate Brownian movement and the force of thermophoretic. Considering a porous substance, a Darcy-Forchheimer theory is implemented, and to simulate non-Newtonian characteristics such as the second-grade model is applied. The complex dimensionality PDE’s in terms of microorganism, energy, momentum and energy are renovated into an ODE by employing suitable similarity variables. The renovating ODEs are tackled through NDsolve technique, and the influence of the newly discovered variable on the microorganism, temperature, concentration and velocity mechanisms has been displayed graphically and in tabular form. It is being suggested that despite growing the magnetic variable, the inertia coefficient and the fluid variable lessen the radial and azimuthal velocity field. The porosity effect and stretching parameter intensify the axial velocity. Additionally, the temperature and concentration augment in tandem with the enhancement of thermal and solutal Biot number. The results of this research seem substantially applicable to spinning biological nanotechnologies production structures, permeable disk devices, thermal energy gadgets, including medical transportation systems wherever accurate oversight of thermal energy, weight, and biological nanofluid transportation is required. The current findings offer valuable scientific insights and highly design advice toward sophisticated rotary disk mechanisms working in permeable, highly conductive conditions.
