    • Aerosol transport in idealized wind-wave systems 

      Åkervik, Espen (2022-12-22)
      This report deals with aerosol transport in turbulent wind over water waves. For simple terrain onshore, there appears to be consensus that aerosol transport is well described by simple models. However, for complex terrain ...

    • 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 ...

    • Literature review of atmospheric contaminant transport offshore 

      Åkervik, Espen; Gjedal, Thor (2023-11-17)
      In this report, we consider the atmospheric dispersion of possibly harmful contaminants from offshore accidents by doing a literature review on the subject. The atmospheric dispersion is mainly governed by the wind, which ...

    • Luftbåren smitte av virale luftveisinfeksjoner fra et aerosolfysisk perspektiv 

      Åkervik, Espen; Fossum, Hannibal E.; Dybwad, Marius; Helgeland, Anders (2020-06-16)
      Luftbåren smitte foregår gjennom at infeksiøst materiale følger med dråper av ulik størrelse ut fra verten gjennom respiratoriske aktiviteter som pust, tale, sang, host eller nys. For de vanlige aktivitetene som pusting, ...

    • Measurements of hydrocarbon flame propagation in a channel 

      Åkervik, Espen; Fossum, Hannibal E.; Henriksen, Mathias; Bjerketvedt, Dag (2021-05-25)
      Assessing the risk of gas explosions associated with Li-ion batteries in confined geometries is challenging. When a Li-ion battery cell undergoes so-called thermal runaway, internal reactions in the cell can lead to the ...
