- The significance of this paper lies in what we have learned about the prediction of the secondary flow field inside aero-engine LP turbines. Simply put the codes used to design such turbines: steady RANS (Reynolds Averaged Navier-Stokes) codes do not predict the secondary flow reliably at all. Today the end wall profiling designed in industry relies on such software: now shown to be a potential problem. The paper also shows that the much more expensive time resolved “URANS” solutions do offer much improved prediction.
