摘要

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.
