A Fully-Mixed Finite Element Method for the n-Dimensional Boussinesq Problem with Temperature-Dependent Parameters

In this paper, we introduce and analyze a high-order, fully-mixed finite element method for the free convection of -dimensional fluids, , with temperature-dependent viscosity and thermal conductivity. The mathematical model is given by the coupling of the equations of continuity, momentum (Navier–St...
