Spectral element simulations of three - dimensional flow and augmented convection in a flat passage downstream from a fully developed channel with symmetric, transverse grooves on opposite walls were performed for 405 <= Re <= 764. Unsteady flow that develops in the grooved region persists several groove - lengths into the flat passage, increasing both local heat transfer and pressure gradient relative to that in a steady flat passage. Moreover, the heat transfer for a given pumping power in the first three groove - lengths of the flat passage was greater than the levels observed in a fully developed grooved passage.
