A pore-scale model for permeable biofilm: Numerical simulations and laboratory experiments
Landa-Marban, David; Liu, Na; Pop, Iuliu Sorin; Kumar, Kundan; Pettersson, Per; Bødtker, Gunhild; Skauge, Tormod; Radu, Florin Adrian (Peer reviewed; Journal article, 2018)In this paper, we derive a pore-scale model for permeable biofilm formation in a two-dimensional pore. The pore is divided into two phases: water and biofilm. The biofilm is assumed to consist of four components: water, ... -
Constrained optimization of offshore wind turbine positions under uncertain wind conditions with correlated data
Pettersson, Per; Aursjø, Olav; Helland, Johan Olav; Jettestuen, Espen (Peer reviewed; Journal article, 2023)Offshore wind power production is subject to substantial uncertainty due to variability in wind conditions. Planning of new wind parks should take these uncertainties into account by means of stochastic modeling and ... -
Dynamic estimates of extreme-case CO2 storage capacity for basin-scale heterogeneous systems under geological uncertainty
Pettersson, Per; Tveit, Svenn; Gasda, Sarah Eileen (Peer reviewed; Journal article, 2022)Geological CO2 storage is expected to grow dramatically in the coming decades to meet global climate targets. Assessment of worldwide storage resources using static methods indicates significant theoretical potential for ... -
Intrusive generalized polynomial chaos with asynchronous time integration for the solution of the unsteady Navier–Stokes equations
Bonnaire, Philip; Pettersson, Per; Silva, Camilo F. (Journal article; Peer reviewed, 2021)Generalized polynomial chaos provides a reliable framework for many problems of uncertainty quantification in computational fluid dynamics. However, it fails for long-time integration of unsteady problems with stochastic ... -
Sampling-Based Methods for Uncertainty Propagation in Flood Modeling Under Multiple Uncertain Inputs: Finding Out the Most Efficient Choice
Hajihassanpour, Mahya; Kesserwani, Georges; Pettersson, Per; Bellos, Vasilis (Peer reviewed; Journal article, 2023)In probabilistic flood modeling, uncertainty manifests in frequency of occurrence, or histograms, for quantities of interest, including the Flood Extent and hazard rating (HR). Such modeling at the field-scale requires the ...
