Navier-Stokes simulations of three - dimensional flow and augmented convection in a channel with symmetric, transverse grooves on two opposite walls were performed for 180 <= Re <= 1600 using the spectral element technique. A series of flow transitions was observed as the Reynolds number was increased, from steady two - dimensional flow, to traveling two and three - dimensional wave structures, and finally to three - dimensional mixing. Three - dimensional simulations exhibited good agreement with local and spatially averaged Nusselt number and friction factor measurements over the range 800 <= Re <= 1600.
