<p>This is an open-access database of experimental data of the flow in a <strong>high-speed low-pressure turbine cascade</strong>. The data have been collected at the <strong>von Karman Institute for Fluid Dynamics</strong> in the period 2018-2022 within the H2020 Clean Sky 2 project <strong>SPLEEN</strong> – Secondary and Leakage Flow Effects in High-Speed Low-Pressure Turbines, a project in collaboration with Safran Aircraft Engines.</p>
<p>This version contains documents that describe the experimental setup, instrumentation, measurement uncertainties, geometries, and database structure.</p>
<p>The database contains experimental data of the test campaign conducted on the linear cascade codenamed SPLEEN C1 in the VKI high-speed wind tunnel S1/C.</p>
<p>The turbine cascade geometry is representative of designs of high-speed low-pressure turbines for next-generation geared turbofan engines.</p>
<p>The measurement datasets describe the <strong>flow through the turbine cascade tested at on- and off-design conditions</strong>, with and without a wake generator located upstream of the cascade, and with and without endwall cavity injection/suction. The database includes measurements of pressure, temperature, flow angles, Mach numbers, pressure loss, unsteady blade and endwall pressure and quasi-shear-stress.</p>
<p><strong>Version v1 </strong>of the database includes measurement datasets performed on the turbine cascade <strong>WITH FLAT ENDWALL (no cavity) WITHOUT WAKE GENERATOR (Steady inlet flow)</strong>. Future versions will also include experimental data of the test case turbine equipped with a wake generator (unsteady inflow with wakes) and endwall cavity flow purge / suction. </p>
<p>The project has received Funding from the Clean Sky 2 Joint Undertaking under the European Union's Horizon 2020 research and innovation program under the grant agreement 820883.</p>
WARNING!
The geometry of the SPLEEN C1 cascade contained in this version (v1) is not correct (wrong cascade stagger angle).
Files affected by this error:
SPLEENC1_Geometry_Airfoil_2D_CAD_v1.igs
SPLEENC1_Geometry_Airfoil_2D_CAD_v1.stp
SPLEENC1_Geometry_Airfoil_2D_CAD_v1.x_t
The coordinates of the SPLEEN C1 geometry provided in the file SPLEENC1_Geometry_Airfoil_2D_v1.xlsx are instead correct.
PLEASE USE version 2 of the SPLEEN C1 CAD files (SPLEENC1_Geometry_Airfoil_2D_CAD_v2)
provided in the new versions of the database.
