Transonic Cascade TEAMAero: Numerical Data Repository

Background The Transonic Cascade TEAMAero (TCTA) is a compressor cascade test case designed at the German Aerospace Center (DLR) via numerical optimization for the TEAMAero research consortium. The cascade has a pitch of 65 mm and a stagger angle of 45.8° with respect to the horizontal axis. The profile shape is provided in this dataset as a .csv file. The cascade's aerodynamic design point has been computed by applying the DLR's TRACE discontinuous-Galerkin large eddy simulation solver for extended analysis. A subset of this data is provided in this repository for interested users. Data description One file containing the primitive variables sampled in the mid-span plane of the simulation domain. The data consists of a uniform grid of 489 by 1000 points (j, i) separated by 0.133 mm and covering one whole pitch (65 mm) of the flow field through the cascade extending from the inlet measurement plane (MP1) to the outlet measurement plane (MP2), see cited literature for more info. Approximately 3.86 ms or 14.4 convective time units (CTUs) of data are provided, sampled at 100 kHz over a total of 387 timesteps (t), starting from t=27 ms and corresponding to the last timesteps calculated in the simulation. The datasets were stored as HDF5 NetCDF files with the xarray Python package.. One csv file containing the profile of the TCTA blade tested in the TGK wind tunnel.
