Abstract
In the present article we discuss double-diffusive natural convective peristaltic flow of Prandtl nanofluid in a two-dimensional porous asymmetric channel. The governing equations for Prandtl nanofluid with double diffusive natural convection are modeled for the first time in the literature. To simplify the problem, an assumption of long wavelength and low Reynolds number is used. A simplified form of problem has been solved numerically using vibrant boundary conditions. Numerical solutions are presented graphically with physical interpretation of stream function, pressure rise, velocity profile, temperature, solutal concentration, and nanoparticle fraction. Numerical solutions also present the physical behavior of the involved fluid parameter.
