Abstract
Effects of swirl brakes on the leakage flow in a centrifugal impeller shroud were investigated by using CFD simulations. Different types of impeller shrouds with or without swirl brakes were modeled and the leakage flow was simulated. Simulations showed that swirl flow strongly interacted with the swirl brakes and that the interaction resulted in rapid and effective loss of angular momentum of the leakage flow.
