Implementation, Demonstration and Validation of a User-Defined Wall Function for Direct Precipitation Fouling in Ansys Fluent

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1497101

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 precipitation fouling from multi-component fluid mixtures that become super-saturated at the wall. The modelling concept involve...

Implementation and Demonstration of a Boundary Condition Wall Function for Direct Precipitation Fouling CFD Modelling

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1358929

In a previous paper we developed a generic modelling framework, for the diffusive mass transport through the turbulent boundary-layer of multi-component, reactive flows where one or more species may deposit on the wall. In the current paper, we describe the implementation of the modelling framework ...

Anaerobic Bio-reactor Modeling

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1371098

EcoLodge aims at providing a proof-of-concept for a new, integrated biotechnological production process for C8 ester butyl butyrate, a promising supplement/substitute for diesel and jet engine fuels, from lignocellulose derived C5 and C6 sugars. Butanol and butyric acid are the process intermediates...
