摘要
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 (Ply). Conclusions are drawn about the upscaling and applicability of the model to full-scale problems, and recommendations are given for optimum application. (C) 2015 Elsevier Ltd. All rights reserved.
