NUMECA Fine / Baldwin-Lomax Turbulence model

A. Beretta

I'm simulating the flow in the diffuser of the impeller of a radial compressor with the NUMECA/Fine Turbo solver. I'm using the Baldwin-Lomax tubulence model. Has anybody some experiece with this turbulence model combined with this flow solver? If yes, can You tell me, for which range of the law-of-the-wall coordinate y+ at the first node from the wall You obtain acceptable results concerning total pressure losses? The manual gives ranges for k-epsilon models but none for Baldwin-Lomax.

Thank You for Your help!
