Abstract

In the current paper, we investigate the entropy analysis of MHD boundary layer flow of copper (Cu)-water based nanofluid along with the porous shrinking wall. Heat transfer analysis is also taken into account with the thermal radiation effects. The single phase nanofluid model is used for the analysis of the effective thermal conductivity. Mathematical modeling is performed to change the physical system into a set of mathematical equations which are further simplified by using suitable variables. Exact solutions for the velocity and temperature profiles are computed and interpreted for diverse physical of interest. It is depicted that by enhancing the magnitude of solid volume fraction and velocity slip parameter of nanoparticles the velocity profile is increased. The results indicate an increment in the Hartman number increases the temperature and thermal boundary layer thickness. It is observed that the entropy generation profile is enhanced by increasing the value of Brinkman number and Reynolds number. The irreversibility parameter is decreasing function of Brinkman number.
