Heat and Mass Transfer Effects on Peristaltic Transport of Eyring Powell Fluid Through an Inclined Non-uniform Channel

The present investigation emphasizes a new attempt at the peristaltic mechanism of Eyring Powell fluid through a non-uniform channel. The flow is analyzed in the presence of wall properties under variable liquid properties, and the mathematical problem for the flow is developed. The channel walls are subjected to slip conditions with low Reynolds number, and long wavelength approximations are employed to simplify the nonlinear governing equations. The nonlinear governing equations are normalized using relevant nondimensional parameters, and the solutions are obtained with the help of the regular perturbation technique. The influence of pertinent physical parameters of interest (velocity, temperature, concentration, and streamlines) are represented graphically. The investigations reveal that the material parameters and elastic parameters of the Eyring Powell fluid model strongly affect the velocity and temperature profiles. The model shows the opposite behaviour in the material parameters A and B in velocity and temperature profiles.
