Calculation of the interface curvature and normal vector with the level-set method
Lervåg, Karl Yngve; Müller, Bernhard; Munkejord, Svend Tollak (Journal article; Peer reviewed, 2013) -
Immersed boundary method for the compressible Navier–Stokes equations using high order summation‐by‐parts difference operators
Ehsan Khalili, M.; Larsson, Martin; Müller, Bernhard (SINTEF Proceedings;2, Chapter; Conference object; Peer reviewed, 2017)A ghost-point immersed boundary method is devised for the compressible Navier–Stokes equations by employing high order summation-by-parts (SBP) difference operators. The immersed boundaries are treated as sharp interfaces ... -
Influence of surfactants on the electrohydrodynamic stretching of water drops in oil
Ervik, Åsmund; Penne, Torstein Eidsnes; Hellesø, Svein Magne; Munkejord, Svend Tollak; Müller, Bernhard (Journal article; Peer reviewed, 2017)In this paper we present experimental and numerical studies of the electrohydrodynamic stretching of a sub-millimetre-sized salt water drop, immersed in oil with added non-ionic surfactant, and subjected to a suddenly ... -
Large time step HLL and HLLC schemes
Prebeg, Marin; Flåtten, Tore Halsne; Müller, Bernhard (Journal article; Peer reviewed, 2018)We present Large Time Step (LTS) extensions of the Harten-Lax-van Leer (HLL) and Harten-Lax-van Leer-Contact (HLLC) schemes. Herein, LTS denotes a class of explicit methods stable for Courant numbers greater than one. The ... -
Large Time Step Roe scheme for a common 1D two-fluid model
Prebeg, Marin; Flåtten, Tore; Müller, Bernhard (Peer reviewed; Journal article, 2017)We present the Large Time Step (LTS) extension of the Roe scheme and apply it to a standard two-fluid model. Herein, LTS denotes a class of explicit methods that are not limited by the CFL (Courant–Friedrichs–Lewy) condition, ... -
Patient Specific Numerical Simulation of Flow in the Human Upper Airways for Assessing the Effect of Nasal Surgery
Jordal, Maria Rolstad; Johnsen, Sverre Gullikstad; Dahl, Sigrid Kaarstad; Müller, Bernhard (SINTEF proceedings;2387-4295, Chapter; Peer reviewed, 2017)The study is looking into the potential of using computational fluid dynamics (CFD) as a tool for predicting the outcome of surgery for alleviation of obstructive sleep apnea syndrome (OSAS). From pre- and post-operative ...
