Abstract

In the present study, an analytical investigation on the effect of complaint walls and chemical reactions on the magneto-hydrodynamic peristaltic pumping of an incompressible viscous fluid is carried out as a model of transport phenomena occurring in the small intestine of human being during digestion process. The mean effective coefficient of dispersion on simultaneous homogeneous and heterogeneous chemical reactions has been deliberated through long wavelength hypothesis and condition of Taylor s limit. The impacts of penetrating parameters on the mean effective dispersion coefficient have been inspected through the graphs. It is noticed that wall parameters (rigidity, stiffness, damping force), and amplitude ratio favor the dispersion, while magnetic parameter resist the dispersion.
