Abstract
This article investigates the thermal-diffusion and diffusion-thermo effects in the peristaltic flow of non-Newtonian fluid in an asymmetric convectively heated channel. The asymmetric nature of the channel here is due to different amplitudes and phases of propagation waves. Mathematical formulation is based on the constitutive relations of third-grade fluid. The solutions of the resulting equations through lubrication approach are given for the stream function, temperature, and concentration. Effects of several parameters of interest are displayed and discussed through plots.
