Issue Date: | 2015 | Abstract: | This paper shows a finite element method for pollutant transport with several pollutant sources. An Eulerian convection–diffusion–reaction model to simulate the pollutant dispersion is used. The discretization of the different sources allows to impose the emissions as boundary conditions. The Eulerian description can deal with the coupling of several plumes. An adaptive stabilized finite element formulation, specifically Least-Squares, with a Crank-Nicolson temporal integration is proposed to solve the problem. An splitting scheme has been used to treat separately the transport and the reaction. A mass-consistent model has been used to compute the wind field of the problem… | URI: | http://hdl.handle.net/10553/16839 | Source: | 4th African Conference on Computational Mechanics. -- Marrakech, Morocco : AfriCOMP'15. -- 7 - 9 January 2015 | Rights: | by-nc-nd |
