MODELLING TRANSITION FOR THE DESIGN OFMODERN AXIAL TURBOMACHINES

The aim of this paper is to investigate whether or not a correlation-based transition model can be used for the design of multistage turbomachinery components. To this end, two components, a low-pressure turbine and an axial compressor, are computed at design and o�-design conditions. The results of the steady computations are compared with experimental data in terms of overall performance and transition occurrence. In all cases, the agreement between the measurements and the computations is good, meaning that the computational setup can be used in a multistage turbomachinery context.
