Numerical Modeling of the Mechanical Reliability of Multicoated Nanoencapsulated Phase-Change Materials with Improved Thermal Performance
Wiley (2021-12-21)Nanoencapsulated phase-change materials (nePCMs) are investigated for enhancing thermal energy storage. However, the shell of these nanocapsules may fail due to stress developed during thermal processes, leading to melting ... -
Numerical modelling and vibration serviceability assessment of a steel footbridge with a significant 3D dynamic behaviour
SAGE Publications (2023-06-19)This paper focuses on the vibration serviceability assessment and numerical modelling of an existing steel truss footbridge located in the outskirts of Castellón, Spain. The footbridge is rather slender and composed by a ... -
Numerical modelling of surface aeration and N2O emission in biological water resource recovery
Elsevier (2024)Biokinetic modelling of N2O production and emission has been extensively studied in the past fifteen years. In contrast, the physical-chemical hydrodynamics of activated sludge reactor design and operation, and their impact ... -
Numerical simulation of gas-liquid flows in a centrifugal rotor
Elsevier (2020-08-10)Two-phase flows generally represent an adverse condition for centrifugal pumps. Research about this topic tends to be focused on performance evaluation through experimental approaches, while numerical works are quite scarce. ... -
Numerical strategies for the Galerkin–proper generalized decomposition method
Elsevier (2013)The Proper Generalized Decomposition or, for short, PGD is a tensor decomposition based technique to solve PDE problems. It reduces calculation and storage cost drastically and presents some similarities with the Proper ... -
Numerical tooth contact analysis of gear transmissions through the discretization and adaptive refinement of the contact surfaces
Elsevier (2016)The tooth contact analysis (TCA) is an important resource for the design of gear drives. This widely used analysis provides the contact pattern, contact path and the function of transmission errors that are directly related ... -
On the basic phenomenon of soil-structure interaction on the free vibration response of beams : Application to railway brigdes
Elsevier (2016-10)The dynamic transverse response of beam type bridges under railway traffic is addressed in this contribution. In particular, how soil-structure interaction may affect the critical or resonant velocities and the associated ... -
On the effects of the fix geometric constraint in 2D profiles on the reusability of parametric 3D CAD models
Springer-Verlag (2018-06)In order to be reusable, history-based feature-based parametric CAD models must reliably allow for modifications while maintaining their original design intent. In this paper, we demonstrate that relations that fix the ... -
On the Existence of a Progressive Variational Vademecum based on the Proper Generalized Decomposition for a Class of Elliptic Parameterized Problems
Elsevier (2018-03)In this study, we present the mathematical analysis needed to explain the convergence of a progressive variational vademecum based on the proper generalized decomposition (PGD). The PGD is a novel technique that was developed ... -
On the One-Dimensional Modeling of Vertical Upward Bubbly Flow
Hindawi Publishing Corporation (2018)The one-dimensional two-fluid model approach has been traditionally used in thermal-hydraulics codes for the analysis of transients and accidents in water–cooled nuclear power plants. This paper investigates the performance ... -
On the relationship between the specific heat enhancement of salt-based nanofluids and the ionic exchange capacity of nanoparticles
Nature Publishing Group (2018)Nanoparticles have been used in thermal applications to increase the specific heat of the molten salts used in Concentrated Solar Power plants for thermal energy storage. Although several mechanisms for abnormal enhancement ... -
On the Role of Geometric Constraints to Support Design Intent Communication and Model Reusability
CAD Solutions (2020)The assurance of model quality in parametric CAD implies that designers must build models that facilitate reuse while retaining their design intent when modified. In this context, a suitable selection of geometric constraints ... -
