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

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...

Anaerobic Bio-reactor Modeling

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...
