CFD-DEM Packed Bed Simulation: OpenFoam Coupling with buoyantPimpleFoam Solver
Dear all,
I plan to do a CFD-DEM simulation of the following physical problem and want to ask for help to decide whether to use YADE or not. Please not that a two-fluids simulation or similar is not possible. It really should be a CFD coupled to DEM for reasons which I cannot elaborate here.
The problem: I want to simulate a moving particle bed, in which an inert gas such as nitrogen, enriched with oxygen, is moving in a counter current way to the particles. The particle movement is downwards (following gravity) and the particles will not fluidize. The particles enter the bed with very high temperatures of 1700K and the inert gas enters at temperatures of 1000K. The particle Reynolds number is low, i.e. between 2 and 80. Depending on the oxygen content, the particles get _reduced _and release oxygen. The particle residence time likely is in the order of minutes.
The goal of the simulation is to know the residence time of the particles, their reduction extent (i.e. oxygen released), and thefinal temperatures at the gas- and particle outlet.
The idea:
My idea so far is to use OpenFoam (in the following abbreviated with OF) together with a DEM software. Initially I started my work with OF 11. Now, I started to look a bit into the CFD-DEM coupling. Due to in-house code, I started with LIGGGHTS. However, the CFDEM coupling between LIGGGGHTs has been updated 7 years ago and requires an OF version 5.x. In other words, kind of outdated and old. Changing from the OF 11 to OF 5.x was/is already a bit tedious.
Now, just a few days ago, I came across an article which compared YADE to LIGGGHTS. As their results are pretty similar, I tought to use YADE instead of LIGGGGHTS.
Before I start with YADE and get frustrated or waste a lot of time (I am a PhD student and dont have that much time), I wanted to ask for your help and input. Therefore I have the following questions. I apologize in advance if they are stupid. I am very new to CFD, DEM and also YADE.
- How is it with solvers? My feeling so far is to use the buoyantPimpleFoam solver in OF. Is this one a) available in the coupled version or do you have b) better ideas?
- Is it correct that the coupling between YADE and OF works with newer OF versions?
- Do you by chance now a good tutorial for newbies?
- Has someone of you maybe a direct comparison between LIGGGHTS and YADE in terms of CFD (OF)-DEM-coupling or knows a good paper?
- As you are experts, how would you proceed?
I thank you very much for your input and hope to get in a fruitful discussion.
