Abstract [en]

This paper introduces an open three-dimensional (3D) flutter test case for steam turbines. The test case is fully described and initial results are presented. The steam turbine last stage blading geometry is taken from a test case originally presented by Durham University. The stage is representative of the aerodynamic characteristics of modern steam turbine blading. To the authors' knowledge, this is the first time that a steam turbine flutter test case is presented based on an open 3D realistic blade geometry. ANSYS CFX and LUFT (Linearized Unsteady Flow solver for Turbomachinery) were both applied to calculate inviscid and RANS steady and unsteady flow solutions. Plots of aerodynamic damping versus inter-blade phase angle and plots of the local work coefficient on the blade for critical cases are presented.
