Based on calculation and analysis, this structure can obviously increase the degree of partial admission in the control stage and reduce the partial admission loss. Meanwhile, it also improves considerably the aerodynamic performance in the cascad end. Through comparvision for three schemes, we have designed a good scheme of the multi-splitter cascade.展开更多
文摘In order to improve the aerodynamic efficiency of steam turbine control stage, the paper presellts multi-splitter cascade structure to be used in the conirol stage. Based on calculation and analysis, this structure can obviously increase the degree of partial admission in the control stage and reduce the partial admission loss. Meanwhile, it also improves considerably the aerodynamic performance in the cascad end. Through comparvision for three schemes, we have designed a good scheme of the multi-splitter cascade.
