✦ Synopsis

Durbin's three transport equation model, the so-called v 2 ±f model, has been implemented in an industrial ®nite element code, N3S, developed at the research and development department of Electricit e de France, enabling the use of unstructured meshes. Validations by comparison with other codes have been performed in the cases of the channel ¯ow at Re s 395, and the backwardfacing step at Re 5100. The test case of the 2D periodic ribbed-channel ¯ow has then been computed, without heat transfer at Re H 37Y 200, and with a constant heat ¯ux imposed at the ribbed-wall at Re H 12Y 600. The results obtained show the ability of the model to predict accurately the enhancement of heat transfer due to the ribs, which is of primary interest for industrial applications.
