Displacement transfer with the mesh deformation method in multidisciplinary optimization of turbine blades

A mesh-deformation-based method was provided in transferring structural displacements to aerodynamics meshes for multidisciplinary optimization of turbine blades. The method focuses on disturbing interior nodes of aerodynamics meshes to keep mesh-quality for the deflected blades. The nodes was disturbed as if they are in a deformed solid under displacement loads. This solid represented the interrelationship of nodes of the aerodynamics meshes. A displacement transfer of a turbine blade was provided. The results indicate that the mesh-deformation-based method work well for the displacement transfer.
