Optimizing thermal characteristics and entropy degradation with the role of nanofluid flow configuration through an inclined channel
Abstract
Recent innovation in micro/nano-scale electronic and thermo-hydro-mechanical-chemical processes, the prerequisite for efficient heat dissipation has become more rigorous, and traditional thermal controlling solutions are facing gigantic challenges. The multi physics related with magnetohydrodynamic interface of thermal and mass diffusion in the converging channel fluid flow makes this study crucial for several advanced applications. Hydrothermal performance of Carreau nanomaterial migration from a source located at the apex of the channel is explored by considering the stimuluses of Lorentz force and constant radiant heat flux. The non-Darcy model includes the consequences due to medium porosity at the channel wall. These structures combined the electrically conducting characteristics of flowing fluid with rheological behavior, propulsion mechanisms and biological geometries. Additional developments in transport mechanism can be accomplished with the deployment of nanofluids, thermal diffusion, and radiant heat. The thermodynamic second law investigation also offers a useful procedure for optimizing thermal performance by degradation of entropy production. The flow problem and entropy optimization mechanism are simulated by implementing a standard computational technique of Keller-Box. The effects produced due to augmenting inertial forces, Lorentz force and porosity over the hydrothermal performance of the fluid migration. The generation of entropy due to diverse contributions also displays reliance on the fluctuating strength of the associated parameters. Velocity develop for sophisticated estimation of Reynold and porosity parameter in a convergent section of the channel. A growth occurs in temperature against Dufour number and radiation parameter. Higher estimation of Soret number leads to the concentration growth, and depressed with Schmidt number. Entropy rate is augmented for radiation effect, ohmic heating and Brinkman number. Nusselt number is upgraded via radiation parameter and Brinkman number.
