A UNIFIED APPROACH TO MIMETIC FINITE DIFFERENCE, HYBRID FINITE VOLUME AND MIXED FINITE VOLUME METHODS [PDF]

open access: yesMathematical Models and Methods in Applied Sciences, 2010
We investigate the connections between several recent methods for the discretization of anisotropic heterogeneous diffusion operators on general grids. We prove that the Mimetic Finite Difference scheme, the Hybrid Finite Volume scheme and the Mixed Finite Volume scheme are in fact identical up to some slight generalizations. As a consequence, some of

Finite volume methods [PDF]

open access: yes, 2000
Publisher Summary This chapter focuses on finite volume methods. The finite volume method is a discretization method that is well suited for the numerical simulation of various types (for instance, elliptic, parabolic, or hyperbolic) of conservation laws; it has been extensively used in several engineering fields, such as fluid mechanics, heat and ...

Perturbative expansions from Monte Carlo simulations at weak coupling: Wilson loops and the static-quark self-energy [PDF]

open access: yes, 2001
Perturbative coefficients for Wilson loops and the static-quark self-energy are extracted from Monte Carlo simulations at weak coupling. The lattice volumes and couplings are chosen to ensure that the lattice momenta are all perturbative.

Calculation of transonic flows around profiles with blunt and angled leading edges

open access: yesVietnam Journal of Mechanics, 2016
Transonic flow is a mixed flow of subsonic and supersonic regions. Because of this mixture, the solution of transonic flow problems is obtained only when solving the differential equations of motion with special treatments for the transition from ...

Improved action and Hamiltonian in finite volumes [PDF]

open access: yes, 1996
We introduce a new Symanzik improved action by adding a 2x2 plaquette in such a way that the Feynman rules in the covariant gauge simplify. We call this the square Symanzik action.

Computational structural dynamics general solution procedure using finite volumes

open access: yesJournal of Algorithms & Computational Technology, 2022
A method for the solution of the three-dimensional structural dynamics equations with large strains using a finite volume technique is presented. The proposed solution procedure is second order accurate in space and employs a second-order accurate dual ...

Probing the chiral weak Hamiltonian at finite volumes [PDF]

open access: yes, 2006
Non-leptonic kaon decays are often described through an effective chiral weak Hamiltonian, whose couplings ("low-energy constants") encode all non-perturbative QCD physics.

The Modelling of the Urea Fertilizer Dissolution Process in Finite/Infinite Volumes of Water [PDF]

open access: yesIranian Journal of Chemistry & Chemical Engineering, 2022
This research aims to provide a model to investigate the impact of some parameters such as impeller speed, temperature, and solid concentration on mass transfer coefficient and the dissolution rate of urea fertilizer in the water.
