Numerical Optimization of the Cross-sectional Shape of Turbine Blades
نویسنده
چکیده
Industrial turbomachinery design requires fast and reliable algorithms for the numerical optimization of design parameters that innuence the ow in the turbomachine. The problem considered in this paper is to determine the cross-sectional shape of a blade in a turbomachine in order to reproduce as well as possible a given velocity proole of the ow around the blade. It is formulated as a least squares minimization problem and solved in a simultaneous optimization approach. The focus of the paper lies on two aspects: (1) the partially reduced SQP method applied to solve the resulting constrained optimization problem and (2) the construction of the multigrid algorithm for the solution of the large scale adjoint systems.

متن کاملA semi-analytical model for velocity profile at wind turbine wake using blade element momentum
The shape of wake behind a wind turbine is normally assumed to have a hat shape for the models used in wind farm layout optimization purposes; however, it is know from experimental tests and numerical simulations that this is not a real assumption. In reality, the results of actual measurements and detailed numerical simulation show that the velocity in wake region has a S-shape profile. The pr...
