Double-Diffusive Natural Convective Peristaltic Flow of a Nanofluid in an Asymmetric Porous Channel

The problem of double-diffusive natural convective peristaltic flow of a nanofluid in an asymmetric porous channel is discussed. The equations for the double-diffusive natural convective nanofluid are modelled first time in the literature and simplified using the long wavelength and low Reynolds number assumptions. The four coupled equations are solved numerically using fourth-order Runge-Kutta-Fehlberg method with a shooting technique. Numerical solutions for stream function, pressure rise, velocity profile, temperature, solutal concentration, and nanoparticle fraction are evaluated and presented through graphs.
