The problems of fluid flow and heat transfer in a turbine disk cavity are highly complex under
rotation-induced Coriolis and buoyancy forces. This study aims to evaluate the influence …

In this study, we numerically investigated the rotor-stator cavity for different disk surface
roughness (rough rotor-RR, rough stator-RS, and rough rotor & stator-RRS) with the aim of …

LIKE many industries, the aviation industry is facing the pressure to break new ground in
engine efficiency to reduce the impacts of an impending climate catastrophe. Not only would …

In the present work, URANS simulations are presented to describe the unsteady interaction
process between the flow ingested/ejected from a cavity system and the main flow evolving …

Ingress is the penetration of hot mainstream gas into the rotor-stator wheel-space formed
between adjacent discs; a rim seal is installed at the periphery of the wheel-space. Purge …

The cavity region between the rotor and stator relies on hardware seals and purge flow to
discourage hot gas path air from being ingested into the unprotected wheel space. However …

Thermal boundary conditions of the turbine disk cavity system are of great importance in the
design of secondary air systems in aero-engines. This study aims to investigate the complex …

Purge flow is bled from the upstream compressor and supplied to the under-platform region
to prevent hot main gas path ingress that damages vulnerable under-platform hardware …

Rim seal structures and sealing flows are essential in aero engines for preventing hot gas
ingestion from mainstream to turbine disk cavities. A novel design method of rim sealing flow …

Ingress is the penetration of hot mainstream gas into the rotor–stator wheel-space formed
between adjacent disks; a rim seal is installed at the periphery of the wheel-space. Purge …
