Modeling the static and dynamic characteristics of a wind turbine airfoil and validation with experimental data

Recent advances in power and efficiency of computerized modeling methods has made it easier to develop accurate tire models. These newer models are now created with such accuracy that it has become easy to predict the experimental tire’s behavior and characteristics. These models are helpful with determining tire, tire-road, and tire-soil interaction properties. By creating virtual models, the overall capital for research and development can be reduced as well as replacing unavailable experimental tires for research. This research paper mainly focuses on the validation of computer generated FEA tire models which are then used for the prediction of the experimental tire’s rolling resistance, static and dynamic characteristics. Experimental data, such as rolling resistance and vertical acceleration are used in validation simulations in order to tune the virtual model to match the experimental tire’s behavior. The tire that was used for this research is a six-groove 445/50R22.5 FEA truck tire, which was constructed and validated over the course of this research.

This paper presents an evaluation of XFOIL and a commercially available CFD solver to predict the two-dimensional lift and drag coefficients of wind turbine airfoil sections for attached and separated flows. The computational solutions are correlated with the experimental data for the DU 96-W-180 airfoil that has been generated from wind tunnel testing performed at TU Delft and TU Berlin. CFD solutions are presented for turbulent calculations using the Shear-Stress Transport (SST) [1] and Spalart-Allmaras [2] turbulence models and transition calculations using the SST γ-θ model. Transition points from the CFD simulations are compared to the results obtained using XFOIL [3]. The paper culminates in a quantitative analysis identifying the deviations of the XFOIL and CFD solutions from the experimental data. This analysis uses the experimental polars generated by TU Delft and TU Berlin as a baseline for the comparison with the end goal of determining the best computational source of design polars for use in industry.
