Entropy generation analysis for axisymmetric flow of Carreau nanofluid over a radially stretching disk

Abstract

In this work, entropy generation impact in an axisymmetric flow of Carreau nanofluid due to a radially stretching sheet has been scrutinized along with non-linear thermal radiation. Both the shear-thickening and thinning of fundamental of Carreau nanofluid have been examined. Buongiorno model is adopted to capture the Brownian motion and thermophoresis influences by the presence of nanofluids. By picking appropriate transformations, constitutive equations of the present problem have been converted into the ordinary differential equation. The reduced system is solved by numerical technique bvp4c. The effect of non-dimensional pertinent parameters against the velocity, entropy, skin friction coefficient, temperature, Nusselt number, Bejan number, Sherwood number, and concentration are talked over and showed with the assistance of graphs and tables. Our obtained results show that entropy generation rises with increasing Brinkman number, magnetic field parameter, Eckert number, temperature difference, and diffusive variable while it declines for the Brownian diffusion parameter.
