Outline of Final Research Achievements |
The experiments were conducted using two types (circular hole and shaped film cooling hole geometries ) of scaled-up model of film cooling holes installed at the bottom surface of a low-speed wind tunnel in order to measure detailed examination of mixing flow features of film cooling air with mainstream. Instantaneous and simultaneous 3-D flow field was measured by LIF and PIV, and time-averaged film cooling effectiveness was measured by PSP. Furthermore, numerical analysis based on Large Eddy Simulation developed by one of the applicant was conducted and the accuracy of numerical analysis is improved by comparison with measured data. The 3-D mixing flow field data and film cooling effectiveness data together with film cooling hole geometries and main flow conditions measured in the wind tunnel were prepared as an open data in web site for the purpose of utilizing as a database for the verification of numerical analysis of film cooling,
