A Dual Mixed Formulation for Non-isothermal OldroydâStokes Problem
No full textWe propose a mixed formulation for non-isothermal OldroydâStokes problem where the both
extra stress and the heat fluxâs vector are considered. Based on such a formulation, a
dual mixed finite element is constructed and analyzed. This finite element method enables
us to obtain precise approximations of the dual variable which are, for the non-isothermal
fluid flow problems, the viscous and polymeric components of the extra-stress tensor, as
well as the heat flux. Furthermore, it has properties analogous to the finite volume
methods, namely, the local conservation of the momentum and the mass
