Area of Research: Aero/Heat Transfer

Federal Project Manager: Mark Freeman

Project Objective: The goal of this multi-year research effort is to explore the possibility of modifying turbine endwall geometries to both increase their aerodynamic performance and reduce the potential for degradation due to deposition. This effort includes both experimental and computational components. The experimental work at BYU will be focused on high temperature deposition experiments, up to 1400C with film cooling capabilty. The BYU facilty will also be adapted to allow elevated diluent (water vapor) concentrations. The OSU facility provides the capability to test actual turbine vane flowpaths at operating temperatures with film cooling. Experimental data from both facilities will provide critical validation for computational models of deposition (developed under this same project.)
