On local cross sections in topological abelian groups
(Springer, 2018)
[Abstract:] We introduce the notion of local pseudo-homomorphism between two topological abelian groups. We prove that it is closely related with the widely studied notions of local cross sections and splitting extensions ...
A reduced-dissipation WENO scheme with automatic dissipation adjustment
(Elsevier, 2020)
[Abstract:] In this paper, we propose a novel modification to the WENO-family schemes to reduce its intrinsic dissipation. In this work, we focus on the WENO5 scheme, which is rewritten in terms of a central plus a dissipative ...
Numerical assessment of fan blades screen effect on fan/OGV interaction tonal noise
(Elsevier, 2020)
[Abstract:] This work deals with sound generation and transmission in a fan stage. The study is done on a subsonic Fan stage and interaction noise between the fan wakes and the Outlet Guide Vanes (OGV) is considered. For ...
Computational modelling suggests complex interactions between interstitial flow and tumour angiogenesis
(Royal Society, 2018)
[Abstract:] Angiogenesis, the growth of capillaries from pre-existing ones, plays a key role in cancer progression. Tumours release tumour angiogenic factors (TAFs) into the extracellular matrix (ECM) that trigger angiogenesis ...
Computer software for analysis and design optimization of power transmission structures by simulated annealing and sensitivity analysis
(Springer, 2021)
[Abstract:] This paper presents a computer software for the optimization of power transmission structures. The software employs a modified version of the Simulated Annealing algorithm that has been proven effective in large ...
Optimization of Offshore Steel Jackets: Review and Proposal of a New Formulation for Time-Dependent Constraints
(Springer, 2020)
[Abstract:] In this work, a methodology for the optimization of offshore wind turbine substructures (jacket type) is presented. The use of a coupled model allows for capturing the full dynamic interaction between all the ...
Very high-order method on immersed curved domains for finite difference schemes with regular Cartesian grids
(Elsevier, 2020)
[Abstract:] A new very high-order technique for solving conservation laws with curved boundary domains is proposed. A Finite Difference scheme on Cartesian grids is coupled with an original ghost cell method that provide ...
Estimation of long-term fatigue damage of fixed substructures using fully-coupled models and non-linear dynamic analysis
(Elsevier, 2020)
[Abstract:] Typical industry models for Offshore Wind Turbines with fixed substructures are based on decoupled models between the wind turbine and the substructure. It is proved that the complete dynamic response of the ...
A high-order finite volume method with improved isotherms reconstruction for the computation of multiphase flows using the Navier–Stokes–Korteweg equations
(Elsevier, 2020)
[Abstract] In this work we solve the Navier–Stokes–Korteweg (NSK) equations to simulate a two-phase fluid with phase change. We use these equations on a diffuse interface approach, where the properties of the fluid vary ...
Smoothed Particle Hydrodynamics: A consistent model for interfacial multiphase fluid flow simulations
(Elsevier, 2018)
[Abstract:] In this work, a consistent Smoothed Particle Hydrodynamics (SPH) model to deal with interfacial multiphase fluid flows simulation is proposed. A modification to the Continuum Stress Surface formulation (CSS) ...
