Abstract
The generation of entropy is correlated with irreversibility of any thermodynamic system. It provides an indication of a loss of energy and therefore a system’s efficiency. Therefore, an attempt has been made to investigate entropy generation and thermal analysis for peristalsis of silver-water nanomaterial through an inclined symmetric channel. The flow is influenced by magnetic field, temperature dependent heat generation/absorption, thermal radiation, mixed convection and viscous dissipation effects. Problem is modelled by utilizing long wavelength approximation. Two phase model of nanofluid is employed. Convective and velocity slip boundary conditions are used. Numerical results are evaluated for axial velocity, heat transfer, Bejan number and entropy generation. Results reveal that velocity of nanofluid decreases by enhancing Hartman number. Addition of nanoparticles volume fraction enhances the temperature of nanofluid. Heat transfer rate at boundary decreases by enhancing velocity slip parameter. Entropy generation increases for radiation parameter and Brinkman number. Further, Bejan number shows increasing behavior when nanoparticles volume fraction is enhanced.
