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

Research output: Contribution to journalArticle

Abstract

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.
