This paper describes the verification examples of the Denton's inviscid fully three-dimensional flow analysis code and Dawes' viscous fully three-dimensional flow analysis code. As for the isentropic Mach number distribution on the vane surface and the total pressure distribution profile at the vane exit, the predicted values by both codes are compared with the experimental values obtained by the annular cascade test. The tested cascade is the first nozzle vane of a high temperature gas turbine, has the features of low solidity, low aspect ratio and meridional constriction, and is considered to have highly three-dimensional flow field. As for the isentropic Mach number distribution on the vane surface, the values predicted by both codes agreed well with the experimental values. The viscous code predicted well the total pressure distribution profile qualitatively.
