Shape Optimization of Labyrinth Seals to Improve Sealing Performance [PDF]

open access: yesAerospace, 2021
To reduce gas leakage, shape optimization of a straight labyrinth seal was carried out. The six design parameters included seal clearance, fin width, fin height, fin pitch, fin backward, and forward expansion angle. The CFD (Computational Fluid Dynamics) model was solved to generate the training and testing samples for the surrogate model, which was ...
