Heat and mass transfer analysis on peristaltic transport of PTT fluid with wall properties

There are several factors that can contribute to the excessive buildup of biofluid in human tissue, including pregnancy, local traumas, allergic reactions, and the use of specific therapeutic medications. As a result, various biomedical applications aim to describe and analyze the wave-like movement of digestion in the small intestinal tract (or organs of the human body), which contains deposits that cause impedance. The novelty of the study lies in the modeling of the chyme forms in the small intestine as Pan-Thien-Tanner fluid (PTT). The current study focuses on analyzing the behavior of the fluid flow, heat, and mass transfer characteristics of the PTT fluid flow analytically. The study employs long wavelength and low Reynolds number assumptions, as the flow is laminar and the radius of the tube is much less than the axial length. The effect of governing parameters of the peristaltic motion of the PTT fluid is explained and elucidated graphically for their various values. The study also examines the effect of increasing Source/Sink parameter values and the Weissenberg number on supporting the fluid flow. The results of the study are crucial for understanding the physiological fluid motion of human organs, such as the chyme movement in the small intestine and esophagus. Furthermore, the results facilitate the development of medical equipment for the treatment of diseases in the organs of the human body.
