Monitoring gas turbine combustors' health, in particular, early detecting abnormal behaviors and incipient faults, is critical in ensuring gas turbines operating efficiently and in preventing costly unplanned maintenance. One popular means of detecting combustors’ abnormalities is through continuously monitoring exhaust gas temperature profiles. Over the years many anomaly detection technologie...

Nowadays, the design and application of free-carbon emission renewable fuels in micropower generators seem to be interesting provide decentralized clean, affordable, resilient energy developing countries, thereby reaching 2050 net-zero carbon objectives. The operation micro-scale Closed Cycle Gas Turbine (CCGT) system with these such as biogas without negatively impacting combustion micro-turbi...

The following paper presents an overview of the Prometheus design system and its applications to gas turbine combustor design. Unlike a traditional “optimizer-centric” method, Prometheus aims to reduce both the level of workflow complexity and rework by taking a more “geometry-centric” approach to design optimization by shifting the control of script generation away from the optimization progra...

KIVA is a widely used (;ode for combustion simulation in engines. We discuss its shortcomings in approximating real gas turbine combustors and what might be done to improve its performance. It is assumed that the combustion and CFD phenomena are modeled with complete accuracy and that the solution of discretized versions of these models is also accurate. Thus the focus is on the geometry, grid ...

The current design of gas-turbine (GT) systems is driven by the need for increased powerdensities, improved fuel-efficiencies, and reduced life cycle costs and environmental impact. Computational techniques have the potential for providing valuable information for the design of GT combustion systems, if adequate models are available. Over recent years, remarkable progress has been made in the d...

This report describes sensing strategies that were developed for monitoring the health and performance of gas turbine combustors. Sensor systems based on these approaches enable control and monitoring systems that improve combustor reliability and operability, achieve optimal performance (e.g., lower NOx emissions) over extended periods of time, reduce maintenance, prevent forced outages, and i...
