Water research, 2015•ElsevierAbstract A novel Euler-Lagrangian (EL) computational fluid dynamics (CFD) finite volume-
based model to simulate the gas mixing of sludge for anaerobic digestion is developed and
described. Fluid motion is driven by momentum transfer from bubbles to liquid. Model
validation is undertaken by assessing the flow field in a labscale model with particle image
velocimetry (PIV). Conclusions are drawn about the upscaling and applicability of the model
to full-scale problems, and recommendations are given for optimum application.
