abstract

The loss and heat transfer of a turbine cascade are strongly influenced by the location and extent of the transitional boundary layer. In this paper, two approaches are adopted to predict the onset and extent of transition within a 2-D explicit Navier-Stokes solution procedure. In the first, transition is predicted by coupling transition data correlations with an algebraic turbulence model. In the second, a low Reynolds Number one-equation turbulence model is used. Comparison is made with the turbine cascade data of Nicholson et al. (1982). This indicates that the first model gives good predictions of suction surface behaviour but poor predictions on the pressure surface. The model is also difficult to apply in a N-S method. The second model gives good predictions of pressure surface behaviour but consistently predicts transition near the leading edge on the suction surface. The latter is attributed to a Mach Number over-speed and leading edge effects.
