摘要

This article incorporates the Darcy Frochheimer peristalsis of CNTs-H2O through tapered half width channel. Here Both linear and nonlinear porous media and mixed convection characteristics are used to carry out fluid flow. Heat generation/absorption, frictional dissipation, Newtonian heating, and linear thermal radiation are all taken into account in heat transfer analysis. In the presence of thermal radiation, analysis of irreversibility caused by heat and fluid friction is also considered through entropy. The large wave-length technique simplifies the flow-formulated system of equations. Then this resulting system is managed through built-in numerical procedure in Mathematica. This built-in method is working under shooting and Rung-Kutta Fehlberg formulas. The graphical analysis of temperature, velocity, pressure gradient, rate of effective heat transfer, and entropy production is thus provided by these numerical results. For both linear and nonlinear permeability parameters, the obtained graphical data demonstrate the opposite behavior of the velocity and pressure gradient. A higher volume proportion of CNTs results in an increase in both Bejan number and entropy.
