Finite-Volume-Particle Methods for Models of Transport of Pollutant in Shallow Water
We present a new hybrid numerical method for computing the transport of a passive pollutant by a flow. The flow is modeled by the Saint-Venant system of shallow water equations and the pollutant propagation is described by a transport equation. The idea behind the new finite-volume-particle (FVP) method is to use different schemes for the flow and the pollution computations: the shallow water e...
متن کاملTransport of Pollutant in Shallow Water a Two Time Steps Kinetic Method
The aim of this paper is to present a finite volume kinetic method to compute the transport of a passive pollutant by a flow modeled by the shallow water equations using a new time discretization that allows large time steps for the pollutant computation. For the hydrodynamic part the kinetic solver ensures – even in the case of a non flat bottom – the preservation of the steady state of a lake...
متن کاملAnti-diffusive finite difference WENO methods for shallow water with transport of pollutant
In this paper we further explore and apply our recent anti-diffusive flux corrected high order finite difference WENO schemes for conservation laws [18] to compute the Saint-Venant system of shallow water equations with pollutant propagation, which is described by a transport equation. The motivation is that the high order anti-diffusive WENO scheme for conservation laws produces sharp resoluti...

چکیده پایان نامه (شامل خلاصه، اهداف، روش های اجرا و نتایج به دست آمده): کار جمع آوری گو یش های محلی در سال های اخیر شتاب امیدوار کننده ای به خود گرفته است. شاید از بارزترین اهداف جمع آوری گویش های مختلف، ثبت و ضبط آن، جلوگیری از نابودی و مهمتر از همه حل مشکلات دستوری زبان رسمی باشد. دقت در فرآیند های زبانی گویش های محلی نوع ارتباط مردم نواحی مختلف با پیرامون نشان را به ما نشان خواهد داد. از س...
A multi-GPU shallow-water simulation with transport of contaminants
This work presents cost-effective multi-GPU parallel implementations of a finite volume numerical scheme for solving pollutant transport problems in bidimensional domains. The fluid is modelled by 2D shallow water equations, while the transport of pollutant is modelled by a transport equation. The 2D domain is discretized using a first order Roe finite volume scheme. Specifically, this paper pr...
