Entropy analysis of non-linear radiative flow of Carreau liquid over curved stretching sheet

Abstract

The objective of the present article is to inquire about the entropy generation in the two-dimensional steady incompressible flow of Carreau liquid over a curved stretching sheet. The heat transfer is characterized by the process of non-linear thermal radiation. The equations were governed through the curvilinear coordinates system which is describing the flow model. The acquired set of equations was converted into non-linear coupled ordinary differential equations utilizing similarity transformation. The governed system was solved via the shooting method employing Runge Kutta Fehlberg (RKF) technique. The interest lies in analyzing the physical quantities like flow velocity, temperature distribution, surface friction, heat flux at wall, and generation of entropy for several involved parameters. The study stated that higher curvature and Carreau liquid parameter enhances temperature distribution and slowdowns the flow. Moreover, the entropy generation enhances fluid parameters and thermal radiation.
