Abstract

In this paper, we have theoretically examined entropy generation inradiative Cross
fluid flow by a slendering stretching sheet with versatile parameters including activation
energy and heat source. Cross model (combination of power-law, Sisko and Williamson
models) is one of the non-Newtonian fluid models, which explains the flow in the regions of
very high and low shear rates along with the power-law region. This model has several
applications, for instance, synthesis of blood and aqueous solution of polymer latex sphere.
The leading equations transmuted as nonlinear ODEs with similarity transmutations and then
resolved numerically with shooting technique (Runge-Kutta 4th order based). Results are
explicatedvia graphs. We have done the validation of our results withearlier promulgated
results (for heat transfer rate). We detected a decorous accord. From the outcomes, we
detected that (i) Weissenberg number escalates velocity profile (ii) heat source parameter
lowers the heat transfer rate (iii) activation energy step-upthe concentration (iv) velocity
power index parameter is helpful to reduce the surface drag force (v) Brinkman number
intensifies the entropy generation.
