摘要：Study the significance of double-diffusive convection and induced magnetic field on peristaltic flow of pseudoplastic nanofluid in a tapered asymmetric channel with different four wave forms have been investigated. Formulation and governing equations of this problem were deduced representing by highly partial differential equations. Hence, exact and analytical solutions of the resulting equations were deduced. Therefore, effects of pressure rise, pressure gradient, temperature, concentration, nanoparticle volume fraction, magnetic force function and stream functions were graphical represented and discussed. It was found that, on rising in the tapered asymmetric channel parameter, the pumping rate increases (decreases) in copumping region (in the retrograde pumping and free pumping regions). Further, the temperature distributions increase with growing in Brownian motion, Soret, Dufour and thermophoresis parameters while the concentration profile decreases with these parameters.
