| Abstract:Non-axisymmetric endwall is applied in the high load turbine design because of efficient reducing the secondary flow loss
and improving the aerodynamic performance of turbine cascade. In this article, the secondary flow model of turbine cascade and methods of
non-axisymmetric endwall contouring are briefly introduced, the aerodynamic performance research progress of high load turbine with nonaxisymmetric
endwall design and the mechanism of suppressing endwall secondary flow were emphatically reviewed, research progress of
the cooling characteristics under function of aerothermal coupling effect of the high load turbine endwall with non-axisymmetric endwall
design was presented, application achievements of the high load turbine non-axisymmetric endwall design technique was summarized, and
further research of the non-axisymmetric endwall design in the aspect of the high efficient aerodynamic and cooling layout of high load
turbine were prospected. |
