Axial Turbine Stage Design: 1D/2D/3D Simulation, Experiment, Optimization — Design of Single Stage Test Air Turbine Models and Validation of 1D/2D/3D Aerodynamic Computation Results Against Test Data

In recent decade, industry had started to use intensively 3D simulation in turbine flow path and its components design. At the same time, this remains a very labor- and time-consumable process that sufficiently hampers its usage, whereas unidimensional and axisymmetric analyses are still widely used in the industry practice. A comparison of the data obtained from experiments conducted on a single stage air turbine test model with the results of 1D and 2D modeling and 3D simulation using a CFD solver was performed. The results were analyzed to validate a judgement of the authors that along with 3D CFD methods the low-fidelity models can be successfully used for turbine flow path optimization with the help of DoE methods. The forthcomings and advantages of different models are also discussed.Copyright © 2005 by ASME
