Project Description

Pennsylvania State University will deliver a computational 3-D model set that can be implemented within current turbine manufacturing design practices. To achieve this, they will first produce four engine-scale turbine cooling passage configurations and cooling hole geometry configurations using additive manufacturing techniques representative of current gas turbine practice. They will then advance, validate, and apply volumetric based Discrete Element Roughness Modeling (DERM) to engine-scale turbine blade cooling passages, and carry out validation quality local flow and heat transfer measurements using geometrically up-scaled hardware in facilities at Baylor University, and then develop optimized designs for cooling passage and cooling hole geometries that accommodate the critically important and mechanistically modeled effects of the complex roughness field that arises in Powder Bed Fusion manufacturing.

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.
