Advanced Turbine Research

Aerodynamics/Heat Transfer

Project goals of  the aero-thermo-mechanical design sector are to assess the unique operation conditions associated with hydrogen turbines and investigate design improvements for addressing these unique design spaces.  Efforts are focused on reducing cooling flows, reducing sealing and leakage flow rates, reducing rotating airfoil count, increasing expansion stage areas, and increasing airfoil length.  These efforts are intended to develop machines that are more efficient with a higher power output.


The combustion program goal is to design and develop the combustion portion of the turbine leveraging the best current and advanced technologies to meet strategic system-level goals of an advanced syngas or hydrogen fueled gas turbine. Efforts are focused on the measurement and assessment of the fundamental properties of hydrogen combustion and the use of these properties to design and develop low-NOx (oxides of nitrogen) combustion systems. Several combustion technologies are under evaluation, including high- and low-swirl pre-mixed, diffusion, hybrid forms of premixed and diffusion, axial staging, rich-lean catalytic, and others.

Materials: Thermal Barrier Coatings

The goal of the projects in the materials sector is to assess and develop thermal barrier coatings (TBCs) that can provide the performance and durability required for use in syngas- and hydrogen-fueled advanced gas turbines. Efforts are focused on identifying candidate TBC architectures and material compositions with the proper thermal, mechanical, and chemical properties for use in reducing heat flux to combustor transition pieces, stationary nozzles, and rotating airfoils. Advanced TBC and bond coat architectures are being developed to improve durability and thermal performance in the harsh environment found in the IGCC gas turbine.
