Thermally Effective and Efficient Cooling Technologies for Advanced Gas Turbines

Project Description

The objective of this University of North Dakota project is to research and develop three cooling methods for improved turbine airfoil cooling performance. The cooling technologies include incremental impingement for the leading edge, counter cooling for the pressure and suction surfaces, and sequential impingement for the pressure and suction surfaces of the vane. These methods are designed to improve the internal thermal effectiveness of the cooling air used before discharging the spent air onto the surface to form an optimal film cooling layer to thermally protect (i.e., reduce the heat load) the surface.

Program Background and Project Benefits

This project will research three cooling methods for improved turbine airfoil cooling performance. Turbine aerodynamics and heat transfer research will develop advanced cooling technology that will allow for higher firing temperatures which translate into increased cycle efficiency. Specifically, this project will investigate incremental impingement for the leading edge, counter cooling for the pressure and suction surfaces, and sequential impingement for the pressure and suction surfaces of the vane.
