TURBO Turbulence Model Validation with Recommendations to Tip-Gap Modeling
Barrows, Sean Thomas

Two new turbulence models have been implemented in the turbomachinery flow simulation code TURBO. This paper focuses on the validation and implementation of the shear stress transportation (SST) model and the detached eddy simulation (DES) model. The models are validated against experimental data as well as results from the current two-equation, low Reynolds number, K-E model. Validation is conducted on a circular cylinder and the NASA transonic compressor rotor, Rotor 35. Cp and St predictions are examined for the cylinder while operating range and performance figures are examined for Rotor 35.

Upon validation, the models are examined for robust performance with regards to the tip-gap modeling of Rotor 35. Currently TURBO standard grids utilize a periodic loss-less tip region. Grid spacing near this region is explored by introducing clustering at the blade tip. A vena-contracta approach and griding of the tip-gap region are also explored.
