Uniform lateral mass flux on natural-convection flow over a vertical cone embedded in a porous medium saturated with a non-Newtonian fluid. (English) Zbl 1159.76381
Summary: A boundary-layer analysis for uniform lateral mass flux effect on the natural convection flow of a non-Darcy, non-Newtonian power-law fluid, along an isothermal cone embedded in a saturated porous medium is investigated. Numerical solutions are obtained for the nonlinear coupled partial differential equations governing the flow using a Keller’s box method. Results for the velocity and temperature profiles as well as the local Nusselt number and velocity at the wall are presented for various values of the mass flux parameter, power-law index, Ergun number, and Rayleigh number. Results are compared with the existing results.
