I. Introduction: Challenges in energy savings for turbines engines Nickel-based superalloys can withstand high temperatures and severe oxidizing conditions, while maintaining superb mechanical properties. Because of this, they are widely used for aerospace and power generation applications. Since higher operating temperature leads to greater cycle efficiency, there are economic and environmenta...

Great strides have been made in monitoring vibration and combustion performance of gas turbine engines. Challenges still remain in the areas of engine overhaul and design/manufacturing of new turbine/generator systems. This paper discusses some elements of current and future efforts to understand what is happening in Real-Time as new engines are run up for the first time after assembly, overhau...

Predictive modelling of turbulent combustion is important for the development of air-breathing engines, internal combustion engines, furnaces and for power generation. Significant advances in modelling non-reactive turbulent flows are now possible with the development of large eddy simulation (LES), in which the large energetic scales of the flow are resolved on the grid while modelling the eff...
