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.
