Mixed Convection Along an Inclined Wavy Surface in a Nanofluid Saturated Porous Medium with Wall Heat Flux

The problem of mixed convection along an inclined wavy surface embedded in a nanofluid saturated porous medium is considered. A coordinate transformation is employed to transform the complex wavy surface to a smooth surface. The governing equations are transformed into a set of partial differential equations using the non-similarity transformation and then applied the local similarity and non-similarity method to obtain coupled ordinary differential equations. These resulting equations are linearized using the successive linearization method and solved by using Chebyshev spectral method. The effects of amplitude of the wavy surface, angle of inclination of the wavy surface, Brownian motion parameter, thermophoresis parameter on the non-dimensional velocity, temperature, nanoparticle volume fraction and heat transfer rate for both aiding and opposing flows are studied and presented graphically.
