2006 article
Finite-volume-particle methods for models of transport of pollutant in shallow water
Chertock, A., Kurganov, A., & Petrova, G. (2006, June). JOURNAL OF SCIENTIFIC COMPUTING, Vol. 27, pp. 189–199.
Contributors: A. Chertock n , A. Kurganov * & G. Petrova *
author keywords: Saint-Venant system of shallow water equations; transport of pollutant; finite-volume schemes; particle methods; central-upwind schemes; balance laws
TL;DR:
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 equations are numerically integrated using a finite-volume scheme, while the transport equation is solved by a particle method.
