WebIn the typical structure of a turboshaft aero-engine, the mass flow of the cooling air in the rotor-stator cavity is controlled by the inlet seal labyrinth. This study focused on the swirl flow and heat transfer characteristics in a rotor-stator cavity with considerations of the inlet seal thermal deformation effect. A numerical framework was established by integrating … WebBearing isolators fitted with dynamic O-rings (right) try to close the gap through which airborne contaminants can enter into the bearing housing. The design intent is for the O-ring to effectively seal off the air gap at standstill (Ref. 2). As the shaft starts rotating, the designers or manufacturers anticipate that centrifugal force acting ...
