Description

Version v2 contains an updated CAD geometry of the SPLEEN C1 cascade (_v2) that corrects a mistake in the airfoil stagger angle. Files affected by this error were SPLEENC1_Geometry_Airfoil_2D_CAD_v1.igs/.stp/.x_t The coordinates of the SPLEEN C1 geometry provided in the file SPLEENC1_Geometry_Airfoil_2D_v1.xlsx are instead correct. Version v3 includes additional measurement datasets collected on the turbine cascade equipped with a wake generator and a flat endwall, as well as with a wake generator and a purged endwall cavity. This version 3 also presents new turbulence and velocity measurements by hot-wire anemometry at the cascade inlet with and without a wake generator. This new data replaces precedent hot-wire measurements included in versions 1 & 2 of this database. This version of the database includes the geometry of the investigated endwall cavity and information on the secondary air system for the cavity purge flow. Updates and minor modifications have been made to the database and the technical notes that complement the test case. Version v4 is a major update to the database with additional time-averaged and time-resolved measurements (pressure and shear stress on the cascade blade and endwall, fast-response probe measurements of inlet and outlet flows, including turbulence) for several cascade configurations and operating conditions. Existing datasets reported in previous versions were also verified and corrected where necessary. This release also includes updates to the technical notes and other complementary files included in this test case.
