Uncertainty quantification in coastal aquifers using the multilevel Monte Carlo method
Alexander Litvinenko, Dmitry Logashenko, Raul Tempone +2
We consider a class of density-driven flow problems. We are particularly interested in the problem of the salinization of coastal aquifers. We consider the Henry saltwater intrusio…
Solution of the 3D density-driven groundwater flow problem with uncertain porosity and permeability
Alexander Litvinenko, Dmitry Logashenko, Raul Tempone +2
As groundwater is an essential nutrition and irrigation resource, its pollution may lead to catastrophic consequences. Therefore, accurate modeling of the pollution of the soil and…
Propagation of Uncertainties in Density-Driven Flow
Alexander Litvinenko, Dmitry Logashenko, Raul Tempone +2
Accurate modeling of contamination in subsurface flow and water aquifers is crucial for agriculture and environmental protection. Here, we demonstrate a parallel method to quantify…
Parareal convergence for 2D unsteady flow around a cylinder
Andreas Kreienbuehl, Arne Naegel, Daniel Ruprecht +3
In this technical report we study the convergence of Parareal for 2D incompressible flow around a cylinder for different viscosities. Two methods are used as fine integrator: backw…
