abstract

This paper attempts to clarify the various definitions of the “S2m” surfaces applied to quasi-3-d inviscid flow computation in turbomachinery by adopting an extended concept of true S2 stream surface (PAG S2) in the discussion. It is indicated that PAG S2 gives a more universal and applicable model to solve the pitch -averaged flow properties through turbine blade passages, especially when a non-orthogonal curvilinear coordinate system is introduced into its governing equations in the present paper.
