Title: Thermally Effective and Efficient Cooling Technologies for Advanced Gas Turbine Systems

Abstract

This report presents the research which has been undertaken under DOE grant DE-FE-0011875 as part of NETL’s UTSR (University Turbine System Research) Program. The experimental portion of this work was undertaken at the University of North Dakota (UND) under the direction of Dr. Forrest Ames. The computational work was undertaken at LSU (Louisiana State University), UM (University of Memphis), and at IIT (Illinois Institute of Technology) under the direction of Dr. Sumanta Acharya. The research program was organized into a four phase program which included: 1) development of a FDA/FEA (finite difference analysis/finite element analysis) cooling model, 2) experimental/computational investigation of appropriate internal cooling methods, 3) experimental/computational investigation of external heat transfer and film cooling, 4) development of an enhanced FDA/FEA model along with the development of a warm cascade test for comparison purposes. The experimental work at UND included research on both internal cooling methods and external heat transfer. The internal cooling work included the design and testing of multiple variable hole-size “incremental impingement” configurations along with testing of two converging rounded diamond pedestal arrays for the trailing edge region. The external heat transfer work included the building of a large scale cascade facility to test a vane designmore » with a large leading edge and an aft loaded suction surface. UND has acquired both midspan and full suction surface heat transfer measurements as well as prepared for film cooling measurements under the grant. LSU/UM/IIT has developed and conducted wall resolved LES computations for the incremental impingement geometries and provided rational understanding of the effect of hole sizes and their distributions. Additionally they have provided design correlations for the incremental impingement heat transfer coefficients. They have also developed LES methods to predict flow through film cooling plenums, which have pedestals along with the development of slot film cooling downstream from the plenums. Additionally, they have developed wall resolved LES to predict vane surface heat transfer including bypass transition without the use of a transition model. Through these simulations they provide understanding of the aerodynamic and surface heat transfer behavior under a range of influences such as freestream turbulence. The present study has produced some very useful research outcomes.« less
