摘要
Abstract
The intermediate stage large enthalpy drop turbine cascades of the sub-critical 600MW steam turbine were experimental studied in a low speed annular wind tunnel.The fluid flow parameter distributions along the blade span and blade pitch were detailedly measured with 5-hole ball head probe under three different incidences.The static pressure coefficients of nine relative blade height were measured in virtue of the static pressure holes of blade surface.Utilizing the ink marks visualization technology, the limit streamlines on the top end wall, hub end wall and blade surface were displayed.The results of experiment show that the large enthalpy drop turbine cascades have a good aerodynamic performance.关键词
