Post-Optimum Sensitivity Analysis with Automatically Tuned Numerical Gradients Applied to Swept Wind Turbine Blades

چکیده
Post-Optimum Sensitivity Analysis (POSA) extends numerical design optimization to provide additional information on how the and performance would change if various parameters constraints were varied. POSA is challenging since it typically requires accurate gradients gradient-based problems that Lagrange multipliers. To overcome this problem, paper introduces a technique automatically tune with statistical methods algorithms calculate multipliers after an optimization. This allows these be applied noisy or solved gradient-free algorithms. These have been swept wind turbine blades. Swept blades can reduce loads by twisting out of when speed increases. The shown introducing freedom in sweep, blade root flap-wise bending moments tip deflection has weaker influence design. Instead, torsion moment material failure become driving constraints.

In this paper a new bucket configuration for a Savonius wind generator is proposed. Numerical analyses are performed to estimate the performances of the proposed configuration by means of the commercial code COMSOL Multiphysicsr with respect to Savonius wind turbine with overlap only. Parametric analyses are performed, for a fixed overlap ratio, by varying the slot position; the results show th...
