"The Thermal and Nuclear Power" Journal, February 2017, B&B-Article in Japanese

B&B-AGEMA GmbH has published a technical article on the newly developed F-CHT analysis to February 2017 issue of "The Thermal and Nuclear Power" Journal. The title is "Frozen-CHT Analysis of the Transient Thermal Behavior and Life Prediction of 700°C Steam Parts". The thermal behavior of a steam by-pass valve subject to cyclic operation with 700°C steam was investigated by newly developed Frozen-CHT approach. The results showed good agreement with measurement results. The approach was applied to transient thermal analysis of a high pressure turbine casing as well.

Star Korean Conference, Seoul, June 2016

Dr. Karsten Kusterer, CEO of B&B-AGEMA, has presented at the Star Korean Conference, 15. June 2016, on "Advanced Design Capabilities for Innovative Cooling Systems of Highest-efficient Industrial Gas Turbines".
Abstract:
Gas turbines are of significant importance in public and industrial power and heat generation. In order to address the diversity of market demands, an industrial gas turbine system of highest efficiency in its class and enhanced operational flexibility has been developed. The key factor in the design process was the application of advanced cooling technologies based on modern computational simulation and analyses systems as provided within Star-CCM+. The complex cooling task is explained for the first vane nozzle of the gas turbine showing simulation results as well as measurement results from the test engine. For higher effectiveness of the film-cooling also an innovative film cooling technology has been developed. Increasing the film cooling effectiveness has been possible by innovative cooling hole geometries and the generation of so-called Anti-Counter-Rotating Vortices (ACRV), which enable the cooling air to remain close to the surface to be cooled. The design parameters of the cooling holes have a crucial impact to the film cooling effectives behind the hole. These design parameters are varied and optimized in order to show the capabilities of the technology. Since the design parameters influence each other and the composition governs the result, an automated optimization tool (Heeds/Optimate+) has been utilized.

Conjugate Heat Transfer Simulations for a Film Cooled Nozzle Guide Vane of a High-efficiency, Industrial Gas Turbine

The 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.
