Peristaltic flow of non-Newtonian fluid through an inclined complaint nonlinear tube: application to chyme transport in the gastrointestinal tract

Acknowledging the novel significances of a peristaltic phenomenon in various biological and physiological systems, researchers in the current decade perform admirable investigations. Studies on this topic still need attention due to the prestigious applications of the peristaltic event in the gastrointestinal tract, artificial lung, heart equipment, and blood circulation in the body. This endeavor explores the novel impact of slip on the peristaltic flow of non-Newtonian Jeffrey liquid through an inclined tube. The effect of varying fluid properties (variable viscosity and variable thermal conductivity) and wall properties is considered. The governing equations are turned dimensionless by appropriate similarity transformations. The series solution is obtained for velocity, temperature, and concentration equation. The graphical representation of pertinent parameters on the physiological flow quantities is depicted by applying MATLAB 2019b program. The obtained results reveal that the up-hosted values of the viscosity parameter enhance distributions of velocity and temperature. Further, the impact of variable viscosity slightly enhances the magnitude of the trapped bolus. Moreover, the present investigation finds its applications to examine the bright insight appliances of chyme through the gastrointestinal tract.
