| Abstract: | Horizontal convection in a rectangular enclosure driven by a linear temperature profile along the bottom boundary is investigated numerically using a spectral-element discretization for velocity and temperature fields. A Boussinesq approximation is employed to model buoyancy. The emphasis of this study is on the scaling of mean Nusselt number and boundary layer quantities with aspect ratio and Rayleigh number. |
