Production/Dissipation Ratio

Hi everybody. Does anybody know what the ratio of production to dissipation looks like for adverse pressure gradient flows in the outer layer of a turbulent boundary layer? In a zero pressure gradient flow this asymptotes to 1, but for adverse pressure gradient the value is bigger. Any references? How does k-epsilon model predicted? Over or underpredictcs? I have some results which predict a higher ratio than standart k-epsilon. I need to verify this. Thanks in advance. John
