Description
Summary:The present study addresses the effects of Hall current and heat generation on peristaltic flow of conducting pseudoplastic fluid in an inclined channel with compliant walls. Mathematical modeling is given in presence of Soret and Joule heating effects. The relevant equations are computed subject to long wavelength and low Reynolds number approximation. Equations containing material parameters are nonlinear. Perturbation technique leads to solution expressions. Graphical results of velocity, temperature, concentration and heat transfer rate are analyzed for the pertinent parameters. Trapping phenomenon is also discussed. •Hall current in peristalsis is formulated.•Pseudoplastic fluid is considered.•Inclined channel is employed.•Compliant wall properties are undertaken.
