Entropy generation for peristaltic motion of Carreau's fluid with mixture of ethylene glycol and boron-nitride nanoparticles

Present work addresses the mixed convective peristaltic transport of electrically conducting ethylene glycol and boron-nitride nanofluids through inclination of asymmetric channel. This investigation also includes the effects of Hall and Ohmic heating. The factor of thermal conductivity is considered to change with temperature. Computations have been done for entropy, temperature, velocity, pressure gradient and concentration by considering the lubrication theory. Analytical solutions of nonlinear system have been computed through homotopy perturbation method. Entropy generation is analyzed graphically under Brownian movement, variable conductivity and thermophoresis aspects. Numeric benchmark of heat mass transport rates is presented. Stresses at the boundaries are examined using bar charts. This research shows that the studied nanofluid presents rise in entropy generation for increase in Hall parameter while reduction is noted when thermal and concentration Grashoff numbers increases. Entropy generation can be controlled at the upper wall when inclination of channel increases but at the same time it rises at the lower wall. Also, the results are found to be in good agreement with the numerical and outcomes reported previously. (paper)
