Peristaltic flow of MHD Casson nanofluid with heat source/sink and thermal radiation

The significance of peristaltic activity in biological and biomedical engineering has recently received a lot of attention. Peristaltic pumping and heat transfer in magnetohydrodynamic biological fluids are fascinating topics with a wide range of physiological applications. These applications include dialysis, medication injection, cardiac surgery equipment, and cancer treatments. In this work, we investigate the characteristics of Casson fluid and peristalsis in a symmetric elastic tube. Buongiorno nanofluid model is taken with the features of thermophoresis and Brownian motion. The heat transfer mechanism is analyzed by acquiring the effects of heat dissipation, absorption/generation, and thermal radiation. A long wavelength is also anticipated when developing the flow model, which is predicated on a short Reynolds number. The non-linear system of equations is numerically solved. Graphical outcomes are acquired to visualize the physical interpretation of several embedded parameters for heat transfer rate, concentration, velocity, and temperature.
