The effect of the Soret and Dufour parameters on the peristaltic transport of a magneto six-constant Jeffreys nanofluids in a non-uniform channel are examined in this research. The mathematical modeling of six-constant Jeffreys nanofluids with double-diffusivity convection and inclined magnetic field is provided with a detailed description. To simplify partial differential equations that are highly nonlinear in nature, the long wavelength and low approximation of the Reynolds number are used. The reduced differential equations are solved by numerical method. The exact temperature, concentration and nanoparticle solutions are calculated. The importance of the various physical parameters of flow quantities is shown in numerical and graphical data. It is observed that the nanosolid particle concentration drops when large values of Brownian motion parameter and Soret number are considered. Furthermore, random collusions transfer molecular kinetic energy into thermal energy during the micro-mixing process of solid nanoparticles within the nanoliquid, resulting in a rise in fluid temperature.
