Recent progress in applying the Large Eddy Simulation (LES) to flow control in turbomachinery is reviewed. The development of flow control in turbomachinery requires accurate prediction of detailed three-dimensional flow structures including unsteady motion of various vortex systems. It has been shown that LES provides more realistic description of the complex flowfields compared to steady and unsteady Reynolds-averaged Navier- Stokes simulations (RANS & URANS).

Based on the proceedings of a symposium on Turbomachinery Fluid Dynamics and Heat Transfer, held at the Pennsylvania State University, University Park, this work offers research results as well as insights into complex flow features found in the turbomachinery used for propulsion, power and industrial applications.
