Three-dimensional boundary layers in turbomachines
Abstract
Various kinds of three-dimensional boundary layer are observed in turbomachines. They are induced by relative motion of a rotor and a stator, by lateral pressure gradient based on curvature of streamlines and by revolution of a rotor. In many cases, secondary flow in boundary layer increases the friction-loss and induces flow separation, as a result the performance of turbomachine is reduced. In some cases separation of boundary layer is delayed by secondary flow and the performance of turbomachine is improved including widening the range of stable operation.
