Results are presented of Bi Global stability analysis of incompressible flow over a row
of T-106/300 Low Pressure Turbine blades. In particular the two- and three-dimensional
stability of a two-dimensional steady state is investigated for Reynolds numbers below
915. Both structured and unstructured meshes have been used at different degrees of
refinement, while variations of the polynomial order of the numerical methods in either
approach have ensured numerical convergence. The flow remains linearly stable to three-dimensional disturbances below Re c . The leading eigenvalues of the flow are obtained in a range of Reynolds and span wise wavenumber
parameters. The two most interesting modes have been found to be related
with the wake of the blade and the separated flow in the trailing-edge region on the suction side of the blade.
