Investigation of mean flow and vertical vorticity in turbulent convection using spectral simulations on massively parallel processors

Direct numerical simulations of Rayleigh-Benard convection are performed at several values of Rayleigh number (Ra). The computational domain consists of a square-planform rectangular box with horizontal-to-vertical aspect ratio equal to four. This domain is periodic in the horizontal directions, and the top and bottom boundaries are isothermal, no-slip, impermeable walls. The flow-fields considered here range from steady horizontally-oriented two-dimensional rolls to unsteady three-dimensional turbulence.
