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 modeling of rim seal flows, especially in terms of unsteady ...

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 ...

Abstract: In the recent years Additive Manufacturing (AM) methods, such as the Direct Metal Laser Melting (DMLM) technology, are getting more and more attractive and feasible for the realization of components and subcomponents of ...
