Design and Verification of Integrated Cooling Effectiveness Test Specimen for Turbine Vane

To make turbine nozzle work reliably, cooling effectiveness test should be firstly conducted tostudy the aerodynamic effect and geometric parameters of film cooling on cooling effectiveness and turbineaerodynamic performance. Based on the principle of similarity,the test specimen adopted simple deck drycombustion constructure. UG parameterized modeling and assembling as well as clearance analysis was ap-plied to reduce the assembling error and interference, and thus improved the efficiency of cooling effective-ness test. Preferable temperature and pressure fields were obtained inside the test specimen, which were ofgood hot-resistance and sealing performance. Matched heat-resistant material made its common wa-ter-cooling construction simpler, shortened half of its process cycle and reduced approximately 60% of itscost.
