Mostly peristaltic study deals with flow in symmetric channels. But there are some physiological systems like uterus where asymmetry plays an important role in transporting Uterine(Etyan and Elad 1999). Previous researchers viz., Jaffrin and Shapiro(1971), Rees(1988), Lagrangian approach, Trapping and reflux, Poiseuille flow, Herschel Bulkley fluid model,
Bingham fluids, Intra- uterine fluid motion, Newtonian fluid, axisymmetric tubes.Srivastava and Srivastava(1995) have studied characteristics like trapping and reflux, channel with flexible porous walls and effects of Poiseuille flow respectively. Later studies by Vajravelu et al. (2005a, 2005b) of bio fluid as Herschel Bulkley fluid paves the way to Mishra and Ramachandra rao(2003) to apply asymmetric channel flow to infra-uterine fluid motion in a non- pregnant uterus. The essence of this paper is about the flow of an incompressible viscous fluid in a vertical asymmetric channel under long wavelength and low Reynolds number. Further in this paper the concentration is upon transport of a conducting viscous fluid with flexible walls with asymmetry being generated by propagation of waves with same speed but with different amplitudes and phases as depicted in the physical models through graphs.
