Heat transfer enhancement in radiative peristaltic propulsion of nanofluid in the presence of induced magnetic field

Abstract

Biomimetics is the imitation of the systems, models, and nature elements for the motive of elucidating complex biological problems. In the current century, the use of nanoparticles in the treatment of biological systems (such as cancer and atherosclerosis treatment) is common in worldwide due to many properties of nanoparticles. In general, the size of nanoparticles are very small so that they can pierce extensively throughout the body. Keeping this in mind, the current article focusses the blood (treated as Phan-Thien-Tanner nanofluid) transport in the intrauterine cavity walls under the various effects such as induced magnetic field and solar radiation. For the formulation, the Cartesian coordinate is used, utilizing appropriate transformations and dimensionless quantities, the dimensional laboratory frame system converted to dimensionless wave frame system. The resulting system of equations are highly nonlinear, so we have used the regular perturbation technique to find the solution. Streamlines, velocity, pressure rise, temperature, and concentration have been plotted to see the blood transport in various situations. It is noticed from our analysis that the external effect of radiation enhances the peristaltic pumping. The nanoparticle temperature and concentration are enhanced with the increase of Brownian motion parameter. The sharp reductions in the induced magnetic field are seen with stronger Hartmann number.
