Three CCPP faculty – Jacqueline O’Connor, Dom Santavicca, and Rich Yetter – were awarded two three-year programs from the Department of Energy National Energy Technologies Laboratory. The NETL press release describes the two programs:
Understanding Transient Combustion Phenomena in Low-NOx Gas Turbines
PIs: Jacqueline O’Connor and Dom Santavicca
Pennsylvania State University will perform research to understand, and eventually predict, unstable combustion resulting from transient operation—the period when a gas turbine changes speed to comply with electricity demand. The project will provide a fundamental understanding of combustion stability during transient operation. The work will also be used to develop a framework to predict, and possibly control, instabilities related to transient amplitude, direction, and timescale.
Effect of Mixture Concentration Inhomogeneity on Detonation Properties in Pressure Gain Combustors
PIs: Dom Santavicca and Rich Yetter
Pennsylvania State University will investigate the effect of fuel and oxidizer mixture properties on the propagation characteristics of the detonation wave in a pressure gain combustion system. This research will help the team improve modeling tools to predict the performance of pressure gain combustors and attain further basic understanding of detonation-inhomogeneity interaction. The results should help improve the design of pressure gain combustion systems, focusing on flow configurations found in rotary detonation engines.
