Ryan Buchta, Arizona State University DOI: A Boussinesq fluid inside a stably thermally stratified square container whose walls are inclined 45 degrees with respect to gravity, with two opposite walls kept at constant temperatures and the other two insulated, is nearly isothermal in the regions above and below the horizontal diagonal. The flow is concentrated in the wall boundary layers and a shear layer centered about the horizontal diagonal. The equilibrium is maintained by the balance between dissipation in the shear and boundary layers, the heat fluxes at the constant temperature walls, and the induced flow resulting from the no-flux condition at the inclined insulated walls. For a small forcing amplitude and below a viscosity-dependent cut-off forcing frequency, this re
