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

Hi Andrew,

Please see this work for our open source code.
