Abstract: The discharge behavior of a “direct-transfer” preswirl system has been investigated experimentally. The influences of the pressure ratio and the swirl ratio as well as the influence of the ...

Abstract: An experimental investigation on the influence of stator rub-grooves on labyrinth seal leakage is presented in the present paper. In current labyrinth seal designs, abradable lands allow the ...

Abstract: The influence of a honeycomb facing on the heat transfer of a stepped labyrinth seal with geometry typical for modern jet engines was investigated. Heat transfer measurements were obtained for ...

Abstract: This paper reports numerical predictions and measurements of the flow field in a stepped labyrinth seal. The theoretical work and the experimental investigations were successfully combined to ...
