Resolution of the flow in clarifiers by using a stabilized finite element method
(John Wiley and Sons, 2004)[Abstract] The description of the flow that takes place in clarifiers and other wastewater treatment basins may be a powerful tool to attain an optimum design of these structures, in order to make the most of the wastewater ... -
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) ... -
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 ... -
SUPG stabilized finite element resolution of the Navier-Stokes equations: application to water treatment engineering
(Elsevier, 2002)[Abstract] In this paper an analysis of the viscous incompressible flow has been carried out, from the very definition of the governing equations, up to the resolution of some practical problems, passing through the ... -
The Impact of the Geometry of the Effective Propped Volume on the Economic Performance of Shale Gas Well Production
(MDPI, 2021)[Abstract] We analyze the effect that the geometry of the Effective Propped Volume (EPV) has on the economic performance of hydrofractured multistage shale gas wells. We study the sensitivity of gas production to the EPV’s ... -
Topological Groups of Lipschitz Functions and Graev Metrics
(Elsevier, 2022)[Abstract] We study the properties of the free abelian topological group Ad(X) on a metric space (X,d) endowed with the topology generated by the Graev extension dˆ of a given metric d on X. We find that the group of ... -
Topology optimization of structures considering minimum weight and stress constraints by using the Overweight Approach
(Elsevier, 2022)[Abstract:] In this paper, a new method for structural topology optimization considering minimum weight and local stress constraints is proposed. For this purpose, the Overweight Approach, an improvement of the so-called ... -
Topology optimization of structures: a minimum weight approach with stress constraints
(Elsevier, 2004)Sizing and shape structural optimization problems are normally stated in terms of a minimum weight approach with constraints that limit the maximum allowable stresses and displacements. However, topology structural ... -
UCNS3D: An open-source high-order finite-volume unstructured CFD solver
(Elsevier, 2022)[Abstract:] UCNS3D is an open-source computational solver for compressible flows on unstructured meshes. State-of-the-art high-order methods and their associated benefits can now be implemented for industrial-scale CFD ... -
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 ... -
WENO Schemes on Unstructured Meshes Using a Relaxed a Posteriori MOOD Limiting Approach
(Elsevier, 2020)[Abstract] In this paper a relaxed formulation of the a posteriori Multi-dimensional Optimal Order Detection (MOOD) limiting approach is introduced for weighted essentially non-oscillatory (WENO) finite volume schemes on ... -
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 ...
