Tóm tắt

Earlier models for flows with drag reduction are reviewed and compared with a new energy-dissipation closure which describes the observed effects of drag reduction on the mean velocity, turbulent energy, and turbulent length-scale distributions, and suggests a new maximum drag reduction law related to the onset of drag reduction.
