Conjugate Heat Transfer Simulations for a Film Cooled Nozzle Guide Vane of a High-efficiency, Industrial Gas TurbineThe conjugate heat transfer (CHT) calculation technique is used for the three-dimensional thermal load prediction of an extensively cooled 1st nozzle test vane installed in a highest-efficient industrial gas turbine. The utilized numerical model contains all geometrical features (e.g. pin-fins, ribs, impingement sheets etc.) of the real test vane without simplifications. The comparison with thermal index paint measurements inside the test engine shows that a qualitatively and quantitatively good agreement between the CHT and the measurements results can be found. A consideration of advanced-shaped film cooling holes at the vane platforms also offers high potential to further reduce the material temperatures and decrease thermal stresses by lowering of platform temperatures and homogenization of the temperature distribution.

Design Space Exploration of Gas Turbine Film Cooling Holes with HEEDS & Optimate+In modern gas turbines, the film cooling technology is essential for the protection of hot parts. Today, shaped holes are widely used, but besides others, the NEKOMIMI-shaped cooling holes have shown that there is still potential to increase the film cooling effectiveness by generation of Anti-Counter-Rotating Vortices (ACRV). As a result, the cooling air remains close to the wall and spreads in lateral direction along the surface. The ACRV result from the special shape of the expanding hole exits (NEKOMIMI-shape). Thus, the design parameters have a crucial impact to the film cooling effectiveness behind the hole. In this study the design parameters are varied and optimized within a multi-objective Pareto optimization in order to show the capabilities of the technology and the potential of HEEDS and Optimate+ for automated design space explorations.
