Effect of a rib on rim seal performance

International Communications in Heat and Mass Transfer, 2014
Abstract The effect of a rib installed in a rim seal on sealing effectiveness was investigated using three-dimensional Reynolds-averaged Navier–Stokes analysis. A parametric study was performed for a single square rib installed on the surface on the rotor side.

A Novel Design of Rim Sealing Flow for Improving Sealing Effectiveness

Journal of Engineering for Gas Turbines and Power, 2023
AbstractRim 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 path based on auxiliary sealing holes and sealing air re-distributions has been proved to improve sealing effectiveness. The present paper uses this method to re-

Effect of Inflow Swirl on the Sealing Effectiveness of Turbine Rim Seal

Volume 7B: Heat Transfer — General Interest/Additive Manufacturing Impacts on Heat Transfer; Internal Air Systems; Internal Cooling, 2023
Abstract Turbine inlet swirl condition is inherently present at the combustion chamber outlet and has an important influence on mainstream flow and gas ingestion. The sealing effectiveness and ingestion mechanism were numerically investigated using Unsteady Reynolds-Averaged Navier-Stokes (URANS) equations coupled with a fully developed ...
