... Abstract Evolutionary advancements and disruptive concepts for future gas turbine-based propulsion systems are researched to reduce the environmental impact of aviation. In the initial design phase, only few data on component efficiencies is available and assumptions have to be introduced...

... Abstract This paper investigates 100%-hydrogen-fuel gas turbines as an enabler for renewable electric power. Intermittent renewables such as solar and wind raise grid problems and impose commercial power limits. Gas turbines running on 100% hydrogen can be the carbon-free grid-supporting...

.... Producing ammonia requires added process steps. There are also impacts when using these fuels in a gas turbine. This paper will examine the issues in using these fuels in two parts. The first phase identifies the technical impacts of operating a gas turbine power plant on 100% hydrogen and 100% ammonia...

... Abstract Can and can-annular (can-type) combustors are widely employed in stationary gas turbines. While majority of combustion instability research so far has focused on single can combustors, studying combustion dynamics in multi-can configurations holds more practical relevance. In can-type...

... Abstract The rim seals of gas turbines are used to control the ingestion of hot mainstream gas into the wheel space between the rotor disk and the stationary casing. Sealing air, which is generally used to pressurize the cavity space, flows through the seal clearance and then mixes...

... Abstract The control of cavities sealing has been a challenging problem since early gas turbine development stages and several aspects regarding the flow physics and the modelling of rim seal flows, especially in terms of unsteady phenomena, still represent an open question. Fundamental test...

... Abstract The use of hydrogen as a fuel for gas turbines is certainly an opportunity to limit greenhouse gas emissions, despite the still not-negligible limitations related to materials and the management of combustion processes. This work aims at proposing a numerical model, developed...

... Abstract One of the most critical phases of designing a competitive product such as a Gas Turbine is the conceptual phase, in particular the definition of the flow path, which decides the performance of the engine. Therefore, the ability to optimize the aerodynamic performance of the flow path...

... Abstract Modern gas turbine engine designers are challenged with aggressive power, cycle efficiency and operational life requirements. Those targets are directly related with turbine inlet temperature, material selection and design choices. Increasing turbine inlet temperature, increases cycle...
