A Higher‑Order Chimera Method for Finite Volume Schemes
(Springer, 2018)
[Abstract:] In this work a higher-order accurate finite volume method for the resolution of the Euler/Navier–Stokes equations using Chimera grid techniques is presented. The formulation is based on the use of Moving Least ...
An a posteriori, efficient, high-spectral resolution hybrid finite-difference method for compressible flows
(Elsevier, 2018)
[Abstract:] A high-order hybrid method consisting of a high-accurate explicit finite-difference scheme and a Weighted Essentially Non-Oscillatory (WENO) scheme is proposed in this article. Following this premise, two ...
Permutations, Signs, and Sum Ranges
(MDPI, 2023)
[Abstract:] The sum range SR[x; X], for a sequence x = (xn)n∈N of elements of a topological vector space X, is defined as the set of all elements s ∈ X for which there exists a bijection (=permutation) π : N → N, such that ...
On the existence of topologies compatible with a group duality with predetermined properties
(Elsevier, 2022)
[Abstract:] The paper deals with group dualities. A group duality is simply a pair (G, H) where G is an abstract abelian group and H a subgroup of characters defined on G. A group topology τ defined on G is compatible with ...
On g-barrelled groups and their permanence properties
(Elsevier, 2019)
[Abstract:] The g-barrelled groups constitute a vast class of abelian topological groups. It might be considered as a natural extension of the class of barrelled topological vector spaces. In this paper we prove that ...
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 ...
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 ...
