Abstract

In this article, solution bounds for velocity and temperature of non-Newtonian nanofluid flow between two vertical flat plates due to natural convection have been investigated in uncertain environment. Governing differential equations of the titled problem contain a physical parameter, namely, nanoparticle volume fraction which is taken as uncertain in terms of interval. The considered problem has been solved by Galerkin’s method where Legendre polynomials are used to approximate the series solution. The terms in the assumed series solutions are orthogonalized by Gram–Schmidt orthogonalization process. The interval uncertainties are converted to crisp form by the help of parametric approach of intervals. The results obtained by proposed method are compared in special cases, viz., with the existing results and they are in good agreement.
