Abstract The present investigation explores the behavior of peristaltic movement of Carreau-Yasuda nanomaterial in curved channel under the influence of radically changing magnetic field. The slip, Joule heating, Brownian motion, thermophoresis, thermal radiation and viscous heating effects are also be accounted. Heat transfer analysis is carried out to understand the energy transfer process. Problem is formulated by using the assumptions of small Reynolds number and long wavelength. Resulting non-linear coupled equations are solved numerically by using built in NDSOLVE in Mathematica. Physical analysis of different flow parameters is carried out through the aid of graphs. Further, it is observed that the Brownian diffusion Nb and thermophoresis Nt effects intensify the heat transfer rate. The opposing results of Brownian diffusion and thermophoresis are noticed for concentration and temperature. Also, results of the straight channel can be obtained by setting k → ∞.
