Study of the turbine rim seal leakage

2017
 The article discusses the turbine rim seal and the processes occurring in it. The basic mechanisms of the hot gas inflow into the internal cavity are described. Features of the rim seal calculate in CFD software are shown. The algorithm of the rim seal calculating in unsteady calculation is created. Transient calculation of the total cavity model with

Rim Seal Experiments and Analysis for Turbine Applications

Journal of Turbomachinery, 1992
An experimental investigation was conducted to determine the sealing effectiveness and the aerodynamic characteristics of four rim seal models for a number of flow conditions. The experiments were conducted to obtain an extended data base for advanced turbine rim seal design. The class of rim seals investigated are those found on the downstream side of
