Numerical and Experimental Investigations on Windage Heating Effect of Labyrinth Seals

AbstractThe heat load caused by windage heating effect of labyrinth seals seriously influences the sealing of shaft air flow. To reveal the windage heating effect of labyrinth seals to reasonably design an aeroengine rotor, this paper studies the windage heating characteristics of labyrinth seals fr...
