Numerical Simulation of Thermal Transportation with Viscous Dissipation for a Peristaltic Mechanism of Micropolar-Casson Fluid

The study of peristalsis in the context of fluid mechanics has received considerable attention in the last few decades, mainly because of its relevance to biological systems and industrial applications. Therefore, a model of micropolar-Casson fluid obeying the peristaltic mechanism with thermal radiation in a symmetric channel using lubrication approximation theory is presented. The impacts of velocity slip and viscous dissipation are considered. The developing dimensionless system of equations is numerically solved using the finite element method. Pumping and trapping characteristics are also inspected. The impacts of abundant dimensionless parameters on fluid flow are featured through graphs. A validity of FEM solutions acquired through MATLAB is also made with the exact solution. To ensure the accuracy of the developed code, obtained results are compared with the results available in the literature and found to be in excellent agreement. Outcomes point out that fluid velocity enhanced for greater values of velocity slip parameter; however, the reverse behavior is observed for the Casson parameter. Moreover, enhancing the behavior of the temperature profile is seen by enhancing the values of the Brinkman number. The results of the present study have potential applications in examining fluid flow in the brain, liquid crystals, exotic lubricants, and the flow of colloidal suspensions as well as in the field of medicine such as drug transport, controlling excessive bleeding during surgeries, and treating tumor/cancerous cells among others.
