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 ...
A very accurate Arbitrary Lagrangian–Eulerian meshless method for Computational Aeroacoustics
(Elsevier, 2018)
[Abstract:] In this work, we propose a new meshless approach based on a Galerkin discretization of a set of conservation equations on an Arbitrary Lagrangian–Eulerian framework. In particular, we solve the Linearized Euler ...
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 ...
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 ...
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) ...
