Dispersion simulation for CBRNE accident coordination training
Vik, Thomas; Gjesdal, Thor; Helgeland, Anders (Forsvarets forskningsinstitutt, 2024-10-09)FFI has developed a virtual training system that can be used to train incident leaders and responders in the mitigation of accidents involving hazardous substances. The virtual training system was successfully used during ... -
Efficacy of face masks as source control and respiratory protection against transmission of SARS-CoV-2
Dybwad, Marius; Fykse, Else Marie; Gjesdal, Thor; Gorzkowska-Sobas, Agnieszka Anna; Helgeland, Anders; Åkervik, Espen (2021-06-25)During the COVID-19 pandemic, medical and community face masks have been used extensively by health care workers and the general public to reduce transmission of the SARSCoV-2 virus. This report reviews the available ... -
On the Use of Computational Fluid Dynamics to Investigate Aerosol Dispersion in an Industrial Environment: A Case Study
Fossum, Hannibal Eie; Reif, Bjørn Anders Pettersson; Tutkun, Murat; Gjesdal, Thor (2012)Aerosol dispersion in the area surrounding an existing biological treatment facility is investigated using large-eddy simulation, with the objective to investigate the applicability of computational fluid dynamics to complex ... -
Simulation of chlorine release in an industrial facility : FLUENT and HPAC model results
Gjesdal, Thor; Bjerkelund, Jens William; Bjerke, Audun (2008)Vi diskuterer utslipp og spredning av klorgass i et industrianlegg. Vi har tatt utganspunkt i et scenario hvor det finnes eksperimentelle referansedata som er oppskalert fra vindtunnellforsøk. Dette tilfellet har blitt ... -
Spectral element benchmark simulations of natural convection in two-dimensional cavities
Gjesdal, Thor; Wasberg, Carl Erik; Reif, Bjørn Anders Pettersson (2004)This report presents the results of spectral element simulations of natural convection in two-dimensional cavities. In particular, a detailed comparison is performed with the reference data recently described by Christon ... -
Variational multiscale turbulence modeling in a high-order spectral element method
Gjesdal, Thor; Wasberg, Carl Erik; Reif, Bjørn Anders Pettersson; Andreassen, Øyvind (2006)One of the more promising recent approaches to turbulence modelling is the Variational Myltiscale Large Eddy Simulation (VMS LES) method proposed by Hughes et al.[Comp. Visual. Sci., vol 3, pp 47-59, 2000]. This method avoids ...
