Computational fluid dynamics modelling of unconfined gas mixing of wastewater sludge in a full scale anaerobic digester

Description

Yes / In this paper, an Euler-Lagrange model for computational fluid dynamics was used
to model a full-scale gas-mixed anaerobic digester. The flow profiles, local values of
non-Newtonian viscosity and average shear rate were analysed. Recommendations to
enhance the effectiveness of mixing were given. In particular, the gas mixing input
power can be reduced without appreciable detrimental effects on the mixing effectiveness.
