Transonic Fan

Identification of Tip-Leakage Vortex Wandering in Large-Eddy Simulation of the ECL5/CATANA Transonic Fan Stage
A large-eddy simulation of the open ECL5/CATANA transonic fan stage uncovers a low-frequency “wandering” motion of the tip-leakage vortex. A dedicated kinetic vortex-tracking algorithm is developed to follow the vortex trajectory and characterise this unsteady behaviour.
