摘要：
The minimization of the secondary losses of a low-pressure turbine row by modifying its end walls, using a gradient-based optimization method is presented. The cavities of the turbine row are included in the simulation and the comparison with the case without cavities is discussed. It is concluded that the presence of the cavity alters significantly the horseshoe vortex and the profiled end-walls just affect the passage vortex and hence larger amplitudes are required to control the flow. A method for the fast and automatic meshing of the domain, which is essential for the optimization process, is also described.
