A Wall-Function Approach for Direct Precipitation/Crystallization Fouling in CFD Modelling
Johnsen, Sverre Gullikstad; Johansen, Stein Tore; Wittgens, Bernd (Chapter, 2015)The main objective of this paper is to present a generic modelling framework, for the diffusive mass transport through the turbulent, reactive boundary layer of multi-component fluid mixtures that ... -
CFD Simulations of Turbulent Flow in the Human Upper Airways
Aasgrav, Elin; Johnsen, Sverre Gullikstad; Simonsen, Are Johan; Müller, Bernhard (Chapter, 2017)In this paper, investigations are conducted using Reynolds-averaged Navier-Stokes (RANS) turbulence models to investigate the importance of turbulence modelling for nasal inspiration at a constant flow rate of 250 ml/s. ... -

Mathematical Modelling and Simulation of Flow in Collapsible Tubes
Akbar, Batool (Master thesis, 2022)Obstruktiv søvnapné (OSA) er en tilstand som midlertidig blokkerer luftstrømmen gjennom de øvre luftveiene under søvn for de som er rammet. Denne vanlige tilstanden kan redusere søvn og livskvalitet, og til og med føre til ... -
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 (Lecture, 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 ... -
