Failure Criterion‐Based Bead Optimization of a Wind Turbine Blade Root Section

open access: yesWind Energy, Volume 29, Issue 2, February 2026.
ABSTRACT This study presents a bead‐based optimization framework for fiber composite wind turbine blades, employing the Tsai–Wu failure criterion as the structural performance measure. The objective is to design an optimal transition geometry between an existing blade and a root section with 20% smaller diameter, while preserving the original material ...

Idealized Offshore Low‐Level Jets for Turbine Structural Impact Considerations

open access: yesWind Energy, Volume 29, Issue 2, February 2026.
ABSTRACT Low‐level jets (LLJs) describe conditions in which the wind speed reaches a local maximum with respect to altitude near the surface; they have been observed intermittently in the US mid‐Atlantic offshore environment. LLJs pose unique operating conditions for future wind turbines operating in the region, such as negative shear and locally ...

Non‐Linear Reduced Order Modelling of Transonic Potential Flows for Fast Aerodynamic Analysis

open access: yesInternational Journal for Numerical Methods in Engineering, Volume 127, Issue 2, 30 January 2026.
ABSTRACT This work presents a physics‐based reduced order modelling (ROM) framework for the efficient simulation of steady transonic potential flows around aerodynamic configurations. The approach leverages proper orthogonal decomposition and a least‐squares Petrov‐Galerkin (LSPG) projection to construct intrusive ROMs for the full potential equation ...
