1 1 Qualitax Project data Title: Desenvolupament d'un aplicatiu d'anàlisi numèrica per determinar la hidrodinàmica i la distribució de clor dins d'un dipòsit d'aigua Company: Centre Tecnològic de l'Aigua (CETAQUA) Period: 01/04/2008 - 31/03/2009 Collaborators: Javier Principe, Christian Muñoz, Shu- Ren Hysing

2 2 Objectives To model the flow within water tanks (for urban use) To account for the demand-supply curves To model the transport, diffusion and decay of chlorine concentrations

3 3 Key numerical ingredients Stabilized FEM for incompressible flows Moving domain (variable demand-supply) treated with and ALE framework Jet boundary conditions Stabilized FEM for the convection- diffusion-reaction equation of chlorine Stiff time integrator schemes
