The objective of this research by The Ohio State University (OSU) is to explore innovative cooling architectures enabled by additive manufacturing techniques to improve cooling performance and reduce coolant waste. The ability to create complex internal geometries will be leveraged to better distribute coolant through microchannels, as well as to integrate inherently unstable flow devices to enhance internal and external heat transfer. Fundamental experiments will be conducted initially to demonstrate and test each of the technologies at large scale and low speed, as well as to determine optimal geometries and operating conditions. These experiments will reveal the most promising and feasible technologies, which will subsequently be incorporated into stereolithography turbine vanes to be tested at appropriate Mach numbers in a high-speed cascade facility. Four cooling schemes have been identified for investigation: fluidic oscillators as pulsed impingement jets, fluidic oscillators as sweeping film cooling holes, micro-channel surface cooling, and reverse film blowing. Finally, a full material system will be demonstrated using a thermal barrier coated, metal deposition fabricated (using Direct Metal Laser Sintering) turbine vane tested at high speed and under high temperature in the turbine test facilities at OSU. The experimental work will be accompanied by a computational fluid dynamics (CFD) study at each stage. These CFD simulations will enable the exploration of a broader design space during the optimization stage, as well as extrapolation to higher temperatures and pressures not possible in the turbine test facility in the final stages. This project leverages previous research under DOE contract DE-FE0007156.
