Thermal radiation and double diffusive effects on bioconvection flow of a nanofluid past an inclined wavy surface

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.

Automated summary

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.
