A direct numerical simulation (DNS) of natural turbulent convection in a differentially heated infinite vertical slot has been computed with a mixed finite difference/Fourier code at Rayleigh numbers of Ra=l.0 105 and Ra=5.4 105 . A database containing up to second-order budgets has been collected,
