A third-order-accurate upwind-biased thin-layer Navier-Stokes zonal code (STAGE-2) has been used to study the unsteady flow in a multiple-stage compressor. In particular, the effects of stator clocking and varying axial gaps on the unsteady flow within a 2-1/2 stage compressor have been investigated. Variations in efficiency, force amplitudes and frequencies were found to be functions of the relative position of the clocked airfoil and convected wake groupings. The following general conclusions can be drawn from the simulations:

Current efforts are focusing on two additional aspects of airfoil clocking:
