Soret and Dufour effects in peristaltic transport of physiological fluids with chemical reaction: A mathematical analysis

The peristaltic transport of Casson fluid in a two-dimensional asymmetric channel with convective conditions is investigated. The Soret and Dufour effects are studied in the presence of chemical reaction. The relevant flow analysis is modeled for Casson fluid in a wave frame of reference. Computations of solutions are made for the velocity, temperature and concentration fields. Here two yield planes exist due to asymmetry in the channel. These planes are calculated by solving the transcendental equation in terms of the core width. Closed form expression of stream function is constructed. Plots are prepared for a parametric study reflecting the effects of Casson fluid parameter, chemical reaction parameter, Prandtl, Schmidt, Soret, Dufour and Biot numbers.
