Abstract: The design of modern gas turbines cooling systems cannot be separated from the use of computational fluid dynamics (CFD) and the accurate estimation of the effect of film cooling. Nevertheless, a complete modeling of film ...

Abstract: The main annulus hot gas ingress into turbine wheel-spaces is still one of the most challenging problems designers face. During the decades, several experimental test benches were developed worldwide to improve the knowledge ...

Abstract: Among internal cooling techniques for gas turbine components, skin cooling is recognized as one of the most promising, especially thanks to the spread of additive manufacturing (AM) techniques. In this regard, several ...

Abstract: Matrix cooling systems are relatively unknown among gas turbines manufacturers of the western world. In comparison to conventional turbulated serpentines or pin–fin geometries, a lattice–matrix structure can potentially ...

Abstract: Among the various types of seals used in gas turbine secondary air system to guarantee sufficient confinement of the main gas path, honeycomb seals perform well in terms of enhanced stability and reduced leakage flow. Due ...

Abstract: Gas turbine design has been characterized over the years by a continuous increase of the maximum cycle temperature, justified by a corresponding increase of cycle efficiency and power output. In such way, turbine components ...

Abstract: Surface roughness is well known to significantly influence turbine aerodynamics and heat transfer; different studies have been undertaken in the last decades, in order to precisely characterize its effects and pursue a ...
