Impacts of Hall current and Joule heating of Cattaneo-Christov on peristaltic stenosed artery of Reiner-Rivlin liquid through Darcy-Forchheimer feature

The primary focus of this research article centers on the investigation of peristaltic transport via stenosed tapered vessels in a fluid governed by the Reiner-Rivlin liquid model. The Cattaneo-Christov temperature model, concentration, The influences of Hall current, Joule heating, Darcy-Forchheimer feature and chemical reaction are deemed. A slip condition governing the velocity distribution is also considered. By employing the Homotopy perturbation procedure, the research simplifies complex partial differential equations into more manageable ordinary differential ones. It is revealed that the pivotal speed dwindles by the rise of the Hartmann number. Also, elevating the Forchheimer factor enhances the velocity. Also, it is detected that the rise in thermal relaxation time produces a decaying influence on the temperature profile. The significance of the problem lies in its diversified medical implementations, including, the flowing of blood influx inside the arteries or urine from kidney to bladder across the ureter.
