Project Description

The Georgia Tech Research Corporation will focus on experimentation and computational model development for large-diameter, multi-nozzle turbine combustors. The work includes a combination of detailed experiments with laser and optical diagnostics that provide high spatio-temporal resolution of the flow, flame heat release, and pressure in a turbine combustor; and reduced order modeling of the flame response coupling with the acoustic field. Reduced order modeling for the flame response using physics-based descriptions of the flame dynamics and a hydrodynamic stability analysis for acoustic-hydrodynamic coupling will enable model development for use in design tools, which will improve turbine operating performance when implemented.

Project Benefits

Anticipated benefits from projects funded through the University Turbine Systems Research (UTSR) Program include development of technologies that will accelerate turbine performance, efficiency, and emissions reduction beyond the current-state-of-the-art and reduce the risk to market for novel and advanced turbine-based power generation. In addition, the UTSR Program seeks to maintain and enhance U.S. university-based turbine science capabilities to ensure a world-class scientific workforce for future generations. UTSR is a component of NETL’s Advanced Turbines Program that manages a portfolio of projects designed to remove environmental concerns over the future use of fossil fuels by developing revolutionary, near-zero-emission advanced turbines technologies.
