Special Issue Information

Dear Colleagues,

Wind turbines are one of the most efficient technologies for producing clean energy and their role in worldwide electricity usage is destined to further grow. At the end of 2018, the installed wind power was around 600 GW, with a yearly increase in the order of 10%.

The development of wind turbine technology requires advanced scientific techniques in the fields of aerodynamics, modeling and simulation, applied statistics, control and monitoring, material science, and applied mechanics.

On these grounds, this Special Issue is collecting contributions about the most recent advances in wind energy science.

The list of possible topics is wide. Some examples include, but are not limited to, developments in the following:

  • Wind turbine technology (aerodynamic and-or control system);
  • Wind turbines control and monitoring (performance evaluation and-or condition monitoring) through data analysis and measurement techniques;
  • Wind farm management and control;
  • Grid integration of wind energy;
  • Offshore wind energy and wind turbine wakes;
  • Onshore wind energy and wind farms in complex terrain;
  • modeling and simulation techniques;
  • Turbulence;
  • Aeroelasticity and loads;
  • Structures and materials;
  • Micro horizontal or vertical axis wind turbines.

As the power output of direct drive generators increases, they become prohibitively large with much of this material structural support. In this work, implicit modeling was coupled to finite element analysis through a genetic algorithm variant to automate lattice optimization for the rotor of a 5 MW permanent magnet direct drive generator for mass reduction. Three triply periodic minimal surfaces (TPMS) were chosen: Diamond, Schwartz Primitive, and Gyroid. Parameter and functionally graded lattice optimization were employed to reduce mass within deflection criteria. Inactive mass for the 5 MW Diamond, Schwartz Primitive, and Gyroid optimized designs was 10,043, 10,858, and 10,990 kg, respectively. The Schwartz Primitive rotor resulted in a 34% reduction in inactive mass compared to a 5 MW baseline design. Radial and axial deflections were below the critical limit of 0.65 and 32.17 mm, respectively. The lowest torsional deflection was seen in the Schwartz Primitive TPMS lattice at 3.89 mm. Based on these designs, hybrid additive manufacturing with investment casting was used to validate manufacturability in metal. A fused deposition modeling (FDM) TPMS topology was printed for validation of the FEA results. Comparison between digital image correlation of the FDM printed design and FEA design resulted in a 6.7% deformation difference for equivalent loading conditions. Full article
