Abstract: Abstract. The flow field developing inside the stator–rotor disc cavities of gas turbines is characterized by highly complex and unsteady behavior driven by strong vortical structures and transient interactions. These ...

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: Abstract. In recent years, research on gas turbine rim seals has shown that the sealing performance is strongly influenced by the inherent unsteadiness of the problem, making it clear that a steady analysis is not sufficient ...

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 ...
