This article analyzes the influence of thermal radiation on double-diffusive natural convection of a nanofluid past an inclined wavy surface in the presence of gymtactic microorganisms. A coordinate transformation and pseudo-similarity variables were used to non-dimensionalize the governing non-linear differential equations, which were then linearized and solved using the bivariate Chebyshev pseudo-spectral collocation method. The effects of physical and geometrical parameters on flow quantities were illustrated and analyzed through graphs.
In this article, the influence of thermal radiation on double-diffusive natural convection of a nanofluid past an inclined wavy surface in the presence of gymtactic microorganisms is analysed. A coordinate transformation is used to transform the complex wavy surface to a smooth surface. Using the pseudo-similarity variables, the governing non-linear differential equations and their associate boundary stipulations are non-dimensionalized. The resulting system of non-linear partial differential equations is linearized using a local linearization method. The obtained linear system of partial differential equations is solved using the bivariate Chebyshev pseudo-spectral collocation method. The effect of pertinent physical and geometrical parameters on the physical quantities of the flow are illustrated through graphs and analyzed.
