Method for the reduction of leakage in labyrinth seals by adapting the seal geometry to match the flow conditions

In this paper a method for reducing leakage in labyrinth seals is presented. This method is based on CFD calculations and consists in the analysis of the phenomenon of gas kinetic energy carry-over in chambers of the seal between gaps. It belongs to the group of geometrical inverse problems and is d...
