Numerical simulation for 3D rotating flow of nanofluid with entropy generation

ABSTRACT

This research article addresses entropy generation in the radiative flow of nanoliquid by considering activation energy and rotating frame. Impacts of viscous dissipation, porous medium, and velocity slip condition are considered for the current analysis. Buongiorno’s model is implemented for nanoliquid transport phenomena. The nonlinear ordinary differential system is developed through transformations. The reduced nonlinear ODEs have been handled with the assistance of BVP4c. Graphs are established to explore the influences of several sundry variables on velocities, nano-concentration, entropy generation, temperature, surface drag coefficients, heat transfer rate, Bejan number, and mass transfer rate. Our main findings indicate that temperature increases against the higher values of a rotation parameter, while an opposite trend is seen in concentration. Another important finding is that entropy generation decreases against the growing values of a porosity parameter. The problem under discussion has significant applications in the food industry and relevance to energy systems, modern technologies of aerospace systems, and biomedical engineering. Nowadays, nanofluid flow problems in a rotating frame have gained immense attention among the research community due to their tremendous applications in technological and industrial sectors. A comparative analysis of current computations with the prevailing literature revealed a remarkable agreement.
