Entropy Optimization on Axisymmetric Darcy-Forchheimer Powell-Eyring Nanofluid over a Horizontally Stretching Cylinder with Viscous Dissipation Effect

The effect of entropy optimization on an axisymmetric Darcy-Forchheimer Powell-Eyring nanofluid flow caused by a horizontally permeable stretching cylinder, as well as non-linear thermal radiation, was investigated in this research work. The leading equations of the current problem were changed into ODEs by exhausting appropriate transformations. To deduce the reduced system, the numerical method bvp4c was used. The outcome of non-dimensional relevant factors on velocity, entropy, concentration, temperature, Bejan number, drag force, and Nusselt number is discussed and demonstrated using graphs and tables. It is perceived that, with a higher value of volume fraction parameter, the skin friction falls down. Likewise, it is found that the Nusselt number drops with enhancing the value of the volume fraction. Moreover, the result reveals that the entropy generation increases as the volume fraction, curvature parameter, and Brinkman number increase.

Automated summary

This research work investigates the effect of entropy optimization on an axisymmetric Darcy-Forchheimer Powell-Eyring nanofluid flow caused by a horizontally permeable stretching cylinder, considering non-linear thermal radiation. The results demonstrate that the increase in volume fraction parameter reduces skin friction and Nusselt number, while increasing entropy generation.
