Abstract:

A Navier-Stokes computer code has been used for the calculation of the three-dimensional secondary flow in a cascade of axial turbine blades. A comparison is made with experiment of the results of various applications of a mixing length model within the code. The results are compared on the basis of mean flow data and also turbulent Reynolds shear stresses. Substantial grid independence was obtained with a grid of 20,000 points further grid refinement had a significant effect only on mids an loss.
