Mixed convective peristaltic transport of Carreau-Yasuda nanofluid in a tapered asymmetric channel

Here modeling and analysis for mixed convective peristaltic flow of Carreau-Yasuda nanofluid have been carried out. The asymmetric channel walls are tapered. Effects of Brownian motion and thermophoresis are taken into consideration. The flow equations for the relevant problem are first constructed and then non-dimensionalized. The resulting non-linear coupled systems subject to lubrication approach are solved. Graphs reflecting the variations of pertinent parameters on the velocity, temperature, nanoparticle volume fraction are examined. Shear stress distribution and pumping and trapping phenomena are discussed. Results indicate that amplitude of shear stress decreases for larger Weissenberg number and power-law index whereas it enhances through viscosity ratio parameter.
