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, 2023Abstract 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 ...

A Novel Design of Rim Sealing Flow for Improving Sealing Effectiveness
Journal of Engineering for Gas Turbines and Power, 2023AbstractRim 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-

Effects of Geometry on Sealing Effectiveness of a Rim Seal
Volume 5C: Heat Transfer, 2014A parametric study has been performed to find the effects of geometric parameters on sealing effectiveness of a rim seal, which is used to prevent the hot gas ingestion into the gas turbine component and to cool the turbine disk. The flow and temperature fields in the reference rim seal which was tested by Popović and Hodson have been investigated ...

The effects of the sealed record in adoption
American Journal of Psychiatry, 1976The authors found that 40 of 50 adult adoptees who had reunions with their birth parents found the experience satisfying. Only 10% of the birth parents reacted adversely, although negative response were somewhat more common among the adoptive parents. These findings confirm the author's belief that adoption practices, which in all but 4 states include ...
