We show that for the P N -P N-2 spectral element method (SEM), in which the velocity and pressure are approximated by polynomials of order N and N -2, respectively, numerical instabilities may occur in Navier-Stokes simulations. These instabilities depend on the formulation of the convection operato

We present the results of a numerical exercise aimed at comparing the predictions of different conventional turbulent modelling approaches for natural convection at Rayleigh numbers characteristic of applications such as energy savings, fire safety or thermal comfort. A twodimensional configuration
A computational study of natural convection of air in a tall rectangular cavity with 4: 1 aspect ratio is conducted. In an effort to investigate the applicability of the Boussinesq approximation to turbulent flow simulation, the cavity is differentially heated from the sides and is insulated at the
