A Keller Box Technique of the Sutterby Nanomaterial Including Gyrotactic Microorganisms Over a Rotating Disk

This work investigates the Sutterby nanofluid due to heated convective boundary features defined across a revolving stretching disk and an applied Darcy-Forchheimer flow. Nanofluids are a mixture of transparent liquids and tiny particles evenly dispersed throughout the base fluid. They have intriguing prospective applications as thermal transfer sources. One of the main purposes of nanofluids is to improve the heat transfer coefficients of base fluids by a considerable amount by the suspension of nanoparticles in the fluids. The Sutterby model, a non-Newtonian fluid, will serve as the foundation for this investigation. Darcy-Forchheimer flow characteristics, heated convective conditions, heat source/sink, chemical reaction, and bioconvection are also taken into account. Appropriate similarity transformations are used to tackle the governing nonlinear differential system. Transformed ordinary differential equations are solved via the Keller box method in the computer program MATLAB. The results of important physical parameters are obtained. Inspirations of important physical parameters are elaborated and briefly studied numerically and visually against the different profiles. The axial, radial, and tangential velocities reduce when the Forchheimer parameter and material parameter increase. Temperature increase in the fluid is a direct consequence of changes in thermal radiation parameters, thermophoresis, and Biot number.
