| Steam turbine plays an important role in China’s energy and in the production of turbine blade, but also related to the development and application of the operation efficiency of steam turbine. With the continuous improvement of the level of turbine blade design, for the backward technology, low Thermal efficiency,the turbine less competitive upgrade technology is very important. Such not only can bring certain economic benefits, can also bring good environmental and social benefits.This paper mainly through the use of Auto CAD, ICEM-CFD, Fluent, Tecplot for the modeling of turbine blade, numerical calculation of grid division, and a series of work after treatment, analysis of different spray angle, dynamic leaf angle, leaf type spacing blade by the lift force size, the most appropriate location to find the relationship between the three. Finally,according to the original blade design a higher performance blade profile.The new one can be reduced by 10 percentage points of pressure loss. To provide some theoretical basis for the design of turbine blade profile. |
