The aim of this paper is to compare viscous predictions for two turbomachinery geometries performed with a simple mixing length turbulence model and a more advanced transport equation approach. The mixing length approach is simple and crude, but cheap; more sophisticated transport schemes are more physical but more expensive. This paper compares the performance of two standard models, in one host code, with experimental data for axial turbine secondary flow development and for axial compressor blade loss-incidence variation. Although the more sophisticated turbulence model does produce detail improvements in the quality of the predictions, as far as loss generation is concerned it is concluded there is little difference between the two models. The reasons for this are discussed in some detail.
