Unsteady flow simulation of turbine stage

The prediction of unsteady, flow field in turbine blades is required by the reduced margin for increasing efficiency, stability and life of propulsion components. Advanced numerical tools are available to run within reasonable time 3D unsteady calculation for full stage. New techniques on the computation and parallel computer allow the improvements of results in terms of cost and accuracy; the physical modelling is sometimes still a challenge and the huge amount of data extracted from experiments require care and skill to beconie useful design tools. A full-3D and parallel unstructured solver has been developed and applied to the simulation Of an Unsteady turbine stage.
