THE FLOW FIELDS IN TWO ANNULAR TURBINE CAJSCADES WERE TESTED IN DETAILS. THE RESULTS SHOWTHAT THE 3-DIMENSIONAL STATIC PRESSURE FIELD IN ANNULAR TURBINE CASCADE REDISTRIBUTES BY USINGTHE CURVED BLADES, WHICH CAUSES THE BLADE CURVING EFFECTS AND ENDWALL VORTEX STRUCTURES TOBEHAVE DIFFERENTLY IN THE TWO ENDWALL REGIONS.“,”The flow fields in two annular turbine cajscades were tested in details. The results showthat the 3--Dimensional static pressure field in annular turbine cascade redistributes by usingthe curved blades, which causes the blade curving effects and endwall vortex structures tobehave differently in the two endwall regions.
