摘要：
Most of the methods attempting the modeling of three-dimensional flows, including secondary and viscous effects, are based on the solution of either the full Reynolds averaged Navier-Stokes equations or the full Navier-Stokes equations. An inviscid three-dimensional code has been developed at VKI and was successively applied to subsonic (5, 6) and transonic flows in single fixed blade rows and to steady transonic flows in axial turbine stages (8). The aim of this contribution is to present a numerical investigation of the three-dimensional rotational flow through a low-speed, low-aspect-ratio, high turning annular turbine nozzle guide vane with meridional tip endwall contouring and to compare these results with detailed measurements obtained at VKI.
