Design of an Improved Turbine Rim-Seal [PDF]
Volume 5C: Heat Transfer, 2015 Rim seals are fitted in gas turbines at the periphery of the wheel-space formed between rotor discs and their adjacent casings. These seals, also called platform overlap seals, reduce the ingress of hot gases which can limit the life of highly-stressed components in the engine.

Unsteady Flow Phenomena in Turbine Rim Seals [PDF]
Volume 5A: Heat Transfer, 2016 While turbine rim sealing flows are an important aspect of turbomachinery design, affecting turbine aerodynamic performance and turbine disc temperatures, the present understanding and predictive capability for such flows is limited. The aim of the present study is to clarify the flow physics involved in rim sealing flows and to provide high quality ...
