Hello guys,
This year we did lots of simulations about the liquid-liquid dispersions in stirred tanks. We employed the semi-conservative two fluid model (implemented in OpenFOAM-2.2.x) and the Quadrature based method of moments to predict the droplet size distribution (DSD). Results: Our results show that the predicted DSD agrees well with the experiments. However, we notice that the predicted Power number by the turbulent model is under-estimated. This comes from the standard k-epsilon turbulence model. This under-estimation is reported extensively in other literature as well. For now we apply a kind of correction on the turbulent energy dissipation rate to handle the problem. For those who are using OpenFOAM to simulate liquid-liquid dispersions, you can check these two papers: AIChE Journal: http://onlinelibrary.wiley.com/doi/1...aic.15557/full Chemical Engineering Science: http://www.sciencedirect.com/science...09250915007642 Now I am investigating the bubble column with the face-based momentum algorithm employing the fully-conservative phase momentum equations. Any comments are welcomed! Best,

Hi Dongyue,
this is a very interesting work! Is the the implementation of your model in OpenFOAM freely available by any chance? Cheers, Andrea |

Please see this work for our open source code. https://www.sciencedirect.com/scienc...10465519303728 Best, Dongyue
