dc.description.abstractThis research investigates characteristics of entropy generation on stagnation point flow of Nimonic 80a nanoparticles over a convectively-heated stretching sheet in porous medium. The Buongiorno model is used for the Nimonic 80a metal nanoparticles of brick shape and includes both tBrownian motion and thermophoresis effect with thermal radiation. Similarity transformation variables are used to simplify the governing flow problem. Numerical solutions for temperature distribution, velocity of fluid, concentration of nanoparticles and entropy profile are established and examined. Moreover, the results obtained from the present methodology are validated when compared with research articles in the existing literature. Excellent agreement is obtained. Expressions for skin friction coefficient and Nusselt number are also taken into consideration and presented via tables.en
