Under the influence of peristaltic propulsion and an induced magnetic field, this article investigates the impact of double-diffusivity convection on Powell–Eyring nanofluids in a non-uniform channel. Firstly, Powell–Eyring nanofluids with induced magnetic field and double-diffusivity convection are mathematically modelled. We apply the principle of long wavelength and approximation of low but finite Reynolds number to optimize PDEs that are extremely nonlinear in behaviour. The exact solution of nanoparticle, concentration and temperature is obtained. The numerical data are graphically analysed using a number of physical parameters of flow quantities.
