Thermal analysis on electromagnetic regulated peristaltic blood-based graphane/diamond nanofluid flow with entropy optimization

Abstract

In the present investigation, the blood mediated nanofluid flow has been studied in the non-symmetric channel driven by peristaltic mechanism. The influence of radiation, electromagnetohydrodynamics and buoyancy forces have been considered into account. The suitable wave and fixed frame transformations and dimensionless parameters have been used to convert the system of dimensional equations to non-dimensional form. Later, the lubrication approach is utilized to simplify the model. The regular perturbation method has been utilized to find the approximate analytical solutions for the velocity, temperature, stream function, pressure gradient, heat transfer rate and entropy production. It is concluded from the current results that, the blood-graphane based nanofluid velocity declined by 21% from slip parameter 0 to 0.05. There is 34% decrement in Bejan number from radiation parameter 0.1 to 0.4 for blood-diamond nanofluid. The temperature of blood-diamond nanofluid enhances by 5% for suspending blade-shaped nanoparticles as compared with sphere-shaped nanoparticles.
