(Master thesis / Masteroppgave, 2009)Numerical simulation of the airflow inside a slowly rotating aerosol chamber is carried out using a high resolution LES and several RANS based turbulence models. The result of the LES revealed a complex turbulent flow field ...

(Master thesis / Masteroppgave, 2013)This thesis investigates numerical methods for pricing options and forward contracts in Continuous Autoregressive Moving Average (CARMA) models. Via the Feynman-Kac connection between Markovian processes and Partial ...
-
(Research report / Forskningsrapport, 2006)Recent work [4] has shown that the Degasperis-Procesi equation is well-posed in the class of (discontinuous) entropy solutions. In the present paper we construct numerical schemes and prove that they converge to entropy ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Landslide tsunamis and impulse waves are hazardous events with severe socioeconomic impacts. A long standing problem with simulations of these events is the generation stage, where landslides and water interact. Depth-averaged ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)The effect of an external magnetic field on the formation of the wake in the potential distribution behind a dust grain is studied with self-consistent Particle-In-Cell numerical simulations. The collisionless plasma flow ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)The charging of a sounding rocket in subsonic and supersonic plasma flows with external magnetic field is studied with numerical particle‐in‐cell (PIC) simulations. A weakly magnetized plasma regime is considered that ...
-
(Doctoral thesis / Doktoravhandling, 2021)Landslides can generate large tsunamis when falling into lakes and the sea. In order to protect coastal areas and communities we need to predict these events. Mathematical models have become a popular method for this task. ...

NUMERICAL SOLUTION OF THE THREE DIMENSIONAL BOUSSINESQ EQUATIONS FOR DISPERSIVE SURFACE WAVES PART 1 (Research report / Forskningsrapport, 1985)
-
(Master thesis / Masteroppgave, 2014)Oppgaven tar for seg den seismiske bølgeligningen i et og to lag med materialer ved hjelp av endelige differanser i tid, og ved bruk av elementmetoden for romlige koordinater. Oppgaven er delt i en serie prosjekter som tar ...
