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) ...
MLS-SPH-ALE: A Review of Meshless-FV Methods and a Unifying Formulation for Particle Discretizations
(Springer, 2023)
[Abstract:] Mesh-based and particle methods were conceived as two different discretization strategies to solve partial differential equations. In the last two decades computational methods have diversified and a myriad of ...
Optimization of Financial Indicators in Shale-Gas Wells Combining Numerical Decline Curve Analysis and Economic Data Analysis
(MDPI, 2024)
[Abstract:] We present a methodology to determine optimal financial parameters in shale-gas production, combining numerical simulation of decline curves and stochastic modeling of the gas price. The mathematical model of ...
Stabilization of numerical formulations for convective-diffussive transport problems
(The International Center of Numerical Methods in Engineering, 2000)
[Abstract] Numerical simulation in Fluid Mechanics is an extremely difficult task, wich complexity increases exponentially as the velocity of the fluid becomes higher. In particular, it is know that serious troubles are ...
SPH-ALE Scheme for Weakly Compressible Viscous Flow with a Posteriori Stabilization
(MDPI, 2021)
[Abstract] A highly accurate SPH method with a new stabilization paradigm has been introduced by the authors in a recent paper aimed to solve Euler equations for ideal gases. We present here the extension of the method to ...
Why do computer methods for grounding analysis produce anomalous results?
(IEEE Power Engineering Society, 2003)
[Abstract] Grounding systems are designed to guarantee personal security, protection of equipments and continuity of power
supply. Hence, engineers must compute the equivalent resistance of the system and the potential ...
Improved δ-SPH Scheme With Automatic and Adaptive Numerical Dissipation
(MDPI, 2020)
[Abstract] In this work we present a δ-Smoothed Particle Hydrodynamics (SPH) scheme for weakly compressible flows with automatic adaptive numerical dissipation. The resulting scheme is a meshless self-adaptive method, in ...
