Peristaltic flow with thermal conductivity of H 2 O + Cu nanofluid and entropy generation

Abstract

a b s t r a c tIn this article, it is opted to investigate the effects of entropy and induced magnetic field for the peristaltic flow of copper water fluid in the asymmetric horizontal channel , the mathematical formulation is presented, the resulting equations are solved exactly. The obtained expressions for pressure gradient , pressure rise, temperature, axial magnetic field, current density, velocity phenomenon entropy generation number and Bejan number are described through graphs for various pertinent parameters. The streamlines are drawn for some physical quantities to discuss the trapping phenomenon.

Analysis of Entropy Generation in Flow of Methanol-Based Nanofluid in a Sinusoidal Wavy Channel

“…For the velocity components U along the X and V along the Y− directions in the fixed frame, one can write V as: The law of conservation of mass, momentum, and energy can be written as [16,37,43,44]: The law of conservation of mass, momentum, and energy can be written as [16,37,43,44]:…”

“…They analyzed that peristalsis is a great entropy generator process, due essentially to dynamic irreversibility. Some more interesting studies in this direction can be consulted in References [36][37][38][39]. Existing literature witnesses that no attention is focused so far on the study of entropy generation on mixed convection [9,[40][41][42][43][44] peristaltic flow in the presence of nanoparticles.…”

Numerical Study of Entropy Generation in Mixed MHD Convection in a Square Lid-Driven Cavity Filled with Darcy–Brinkman–Forchheimer Porous Medium

“…They showed that the entropy generation approaches zero near to the free stream region. Akbar et al [15] presented the effect of the entropy and the magnetic field on the peristaltic flow of the copper water fluid in an asymmetric horizontal channel. They showed that the entropy generation number increases with the Brinkman number.…”

Entropy Generation on MHD Casson Nanofluid Flow over a Porous Stretching/Shrinking Surface

“…Abolbashari et al [24] have investigated analytically the fluid flow with heat and mass transfer and entropy generation for the steady laminar non-Newtonian nanofluid induced by stretching sheet in the presence of velocity slip and convective surface boundary condition. Few more attempts are taken into account of entropy generation on nanofluid with stretching surface with different geometry [25][26][27][28][29].…”
