Impact of ciliated walls on peristaltic flow of Rabinowitsch fluid through flexible tube with heat/mass transfer
Abstract
Current work focuses attention on discussing the peristaltic flow of Rabinowitsch fluid through ciliated walled inclined circular tube. The related mathematical equations are modelled in the presence of thermal radiation and connective conditions at the boundaries. In addition, mass transfer with Soret effects is also given consideration. Lubrication approach is adopted for simplification of the nonlinear set of equations. The resulting equations are then solved exactly by implementing various command of MATHEMATICA subject to relevant boundary conditions. Results are discussed for various flow quantities like velocity (u), temperature (θ), concentration (φ), pressure gradient (dp/dz), pressure rise (Δp) and heat transfer (Z). The effect of various parameters on velocity are discussed separately for shear thinning and shear thickening fluid in detail. Convective heat transfer is found to be greater at the boundaries resulting in decreased temperature there.
