Multiscale Geometric Integration of Deterministic and Stochastic Systems [PDF]

, 2011
In order to accelerate computations and improve long time accuracy of numerical simulations, this thesis develops multiscale geometric integrators. For general multiscale stiff ODEs, SDEs, and PDEs, FLow AVeraging integratORs (FLAVORs) have been ...

Multiscale Flow Simulation by Adaptive Finite Volume Particle Methods [PDF]

PAMM, 2005
AbstractWe report on recent developments concerning adaptive finite particle methods, which are used for the numerical simulation of multiscale phenomena in time‐dependent evolution processes. The proposed concept relies on a finite volume approach, which we combine with WENO reconstruction from particle average values.

A Stabilized Finite Element Framework for Anisotropic Adaptive Topology Optimization of Incompressible Fluid Flows

Fluids, 2023
This paper assesses the feasibility of performing topology optimization of laminar incompressible flows governed by the steady-state Navier–Stokes equations using anisotropic mesh adaptation to achieve a high-fidelity description of all fluid–solid ...

Direct Simulation of Fluid Transport at Solid Interfaces with a Multiscale Lattice-Boltzmann Finite-Volume Method

Applied Rheology, 2004
It is shown that the combined use of a mesoscopic lattice Boltzmann solver with finite-volume techniques, both enriched with local-refinement (multiscale) capabilities, permits to describe transport phenomena at fluid-solid interfaces to a degree of ...

Multiscale Simulation of 2D Heat Transfer in Composite Media Based on Global–Local Enrichment Functions

Mathematics
In this study, the extended finite element method (XFEM) was integrated into the generalized multiscale finite element method with global–local enrichment (GFEMgl) to simulate 2D heat conduction in highly heterogeneous materials (i.e., matrixes with ...

A higher order control volume based finite element method to prodict the deformation of heterogeneous materials [PDF]

, 2013
Materials with obvious internal structure can exhibit behaviour, under loading, that cannot be described by classical elasticity. It is therefore important to develop computational tools incorporating appropriate constitutive theories that can capture ...

A Multiscale Compositional Numerical Study in Tight Oil Reservoir: Incorporating Capillary Forces in Phase Behavior Calculation

Applied Sciences
Tight oil reservoirs offer significant development potential. Due to the pronounced capillary forces in their nanopores, phase behavior differs markedly from that in conventional reservoirs, challenging traditional equations of state and numerical ...
