Pragmatism in industrial modelling, applied to "ladle lifetime in the steel industry"
Stein Tore Johansen, Bjørn Tore Løvfall, Tamara Rodriguez Duran +1
A methodology for building pragmatic physics based models (Zoric et al., 2015b) is here adapted to a use-case in the steel industry. The challenge is to predict the erosion of stee…
Pragmatical physics-based model for ladle lifetime prediction
Stein Tore Johansen, Bjørn Tore Løvfall, Tamara Rodriguez Duran
In this paper we develop a physics-based model for the erosion of lining in steel ladles. The model predicts the temperature evolution in the liquid slag, steel, refractory bricks…
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…
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…
