An exploration of diffusion-thermo and radiation absorption impacts on non-Newtonian MHD flow towards two distinct geometries with biot number
Abstract
Temperature and liquid flow monitoring are required in many industrial applications in order to maximize machine performance. When exploring polymers, fabricating synthetic films and transparent materials, and manufacturing metal-based equipment, frictional forces and thermal flow rates need to be controlled. The significance of the study of prominent characteristics of Diffusion-Thermo, Quadratic thermal radiation and radiation absorption over a permeable stretching geometry are discussed. Similarity transformations reduced the boundary layer partial differential to an ODE. The acquired system of ODEs is solved in numerical-manner using MATLAB bvp4c. The distributions f '(η), θ(η) and φ(η) are described graphical aspect, with specified governed parameters. As Diffusion thermo parameter raises, temperature field enhances. As radiation absorption raises, the temperature and velocity enhance and concentration decreases. A rise in radiation absorption parameter causes a raise in the buoyancy, which in turn raises the flow rate, and that this is reflected in the velocity profiles. The radiation absorption parameter raises temperatures nearer porous boundary layer and lowers concentration. Rising temperature ratio parameter θw values were accompanied by rising temperatures. Temperature is enhancing when improving of Biot parameter. The skin-friction is heightened with raising ‘n’ values. Nusselt number is declined, raising values of Df. The Sherwood number is enhanced with raising values of ‘Sc’. An incorporation of Diffusion thermo, Quadratic thermal radiation and radiation absorption effects in a nano-Carreau flow across Wedge and Cone is the novelty. The flow of a boundary-layer across a wedge gets made growingly significant, not long ago, owing to its many practical applications, including those in medical, bioengineering, crude oil extraction, nuclear power plants, a polymer extrusion process, production of plastic sheet, metal spinning, friction drag of a ship, and electronic gadgets, etc. This study will be extended by incorporating micro-polar, tangent hyperbolic, Sutterby, with distinct non-Newtonian fluids.
