On Diffusion-Induced Non-Constant Composition Profiles in the Boundary Layer of Inert Multicomponent Mixtures
Sverre G. Johnsen
In the boundary layer of multicomponent fluid mixtures, the species-specific mass flux in the wall-normal direction is determined by the combination of turbulent-diffusiophoretic d…
A Review of Experimental Solubilities and a General Correlation between the Temperature-Dependent Solubility and Solute and Solvent Molar Masses for Binary n-Alkane Mixtures
Sverre Gullikstad Johnsen
The solubility of a "heavy" alkane (solute) in a "light" alkane (solvent) is generally temperature dependent. Moreover, it is determined by the molar masses of the solute and solve…
On the Rheology of Newtonian Single-Phase Multicomponent Mixtures
Sverre Gullikstad Johnsen
In the turbulent boundary layer of multicomponent fluid mixtures, the species-specific mass flux is determined by the combination of turbulent-diffusiophoretic diffusion and diffus…
A wall-function approach for direct precipitation/crystallization fouling in cfd modelling
Sverre Gullikstad Johnsen, Stein Tore Johansen, Bernd Wittgens
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 flu…
Patient specific numerical simulation of flow in the human upper airways for assessing the effect of nasal surgery
Maria Rolstad Jordal, Sverre Gullikstad Johnsen, Sigrid Kaarstad Dahl +1
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 syndr…
CFD simulations of turbulent flow in the human upper airways
Elin Aasgrav, Sverre Gullikstad Johnsen, Are Johan Simonsen +1
In this paper, investigations are conducted using Reynolds-averaged Navier-Stokes (RANS) turbulence models to investigate the importance of turbulence modelling for nasal inspirati…
Implementation, demonstration and validation of a user-defined wall-function for direct precipitation fouling in ANSYS Fluent
Sverre G. Johnsen, Tiina M. Pääkkönen, Stein Tore Johansen +2
In a previous paper (Johnsen et al., 2015) and presentation (Johnsen et al., 2016), we developed and demonstrated a generic modelling framework for the modelling of direct precipit…
On the wall boundary conditions for species-specific mass conservation equations in mathematical modelling of direct precipitation fouling from supersaturated, multi-component fluid mixtures
S. G. Johnsen, T. M. Pääkkönen, S. Andersson +2
The mathematical modelling of species transport in the turbulent boundary layer of fluids that precipitate on the wall, is an important topic at the heart of one of the biggest cha…
