| Abstract: | Considering distortions of the stream surface and through the search for suitable axial velocity distributions in controlled vortex design stage,a 1.5-stage subsonic axial flow turbine is designed by controlled vortex design method with the given pressure distributions to resolve circulation distributions.The turbine blades are then obtained through parameterization design and are numerically studied through 3D viscous simulation finally.The results show that this controlled vortex design method relieves th... |
