| Popis: |
In this work the flow through a pre-swirl turbine guide vane was calculated using two different flow solvers and compared with total pressure measurements in a downstream plane. The flow is transonic and strongly influenced by secondary flows. A special feature of this cascade is that the gap height at the hub is varying. Flow separation and leakage vortex flow dominate the loss generation. The flow is simulated using an in-house CFD code as well as the commercially available code FLUENT. The flow is carefully analysed and the loss generation mechanisms are presented in detail. The comparison with the measured total pressure distribution shows that the overall loss scheme is well predicted by both codes, but there are still large deficiencies in the quantitative results. The commercial code FLUENT is closer to the measurement data. Further investigations are performed to find out the differences between both codes. |
