A finite element method for simulating soft active non-shearable rods immersed in generalized Newtonian fluids
Ausas, Roberto Federico; Gebhardt, Cristian Guillermo; Buscaglia, Gustavo Carlos (Journal article; Peer reviewed, 2022)We propose a finite element method for simulating one-dimensional solid models with finite thickness and finite length that move and experience large deformations while immersed in generalized Newtonian fluids. The method ... -
Gone with the wind? Wind farm-induced wakes and regulatory gaps
Finserås, Eirik; Herrera Anchustegui, Ignacio; Cheynet, Etienne; Gebhardt, Cristian Guillermo; Reuder, Joachim (Journal article; Peer reviewed, 2024)Wind farm-induced wakes can propagate dozens of kilometres, decreasing the power production and the fatigue lifetime of wind turbines between neighbouring farms. This phenomenon termed hereinafter “wind theft”, may lead ... -
On a nonlinear rod exhibiting only axial and bending deformations: mathematical modeling and numerical implementation
Gebhardt, Cristian Guillermo; Romero, Ignacio (Journal article; Peer reviewed, 2021)In this work, we present the mathematical formulation and the numerical implementation of a new model for initially straight, transversely isotropic rods. By adopting a configuration space that intrinsically avoids shear ...
