Setting up MultiPhysic EDEM-Acusolve Coupling

harold leon_20419

Hello everybody,

I am from Chile and i am trying to setting up a simulation that could run an acusolve-EDEM coupling and the fenomenom is described next:

I need to simulate how bulk material whitch is falling in to a chute are mixing with a portion of water (agua) who is added by a pipe in the midle of the chute and review the next points:

.the cohesion effects due to the mix (zona de mezcla) between water and bulk material

.the wear in equipments due to the impact of the bulk material

.the duct blockage at the end of the chute due the mix (water-bulk material)

Is necesary to understand that the chute never will full of water, the water will run into a little portion of the control volume.

Hi Harold,

Thanks for raising this question.

In EDEM it is possible to define a liquid content as a particle property and relate ths to the inter-particle adhesion via the EDEM Applicaitons Programming Interface. However, this apporach is only valid for relatively low liquid volume fractions (around <20%). Beyond that the water and bulk solid mixture becomes a slurry and inter-particle adhesion is no longer a funciton of liquid content. If this is  the case, then you can model particle adhesion using the built-in JKR contact model.

I'm adding in @Ravi Teja Chaganti to comment further on feasibility from the AcuSolve side.

Best regards,

Stefan

Hi Stefan and thank you for your answer.

I believe that in this case, regardless of the percentage of water, a coupled simulation is necessary, due the "bulk solid -water mixture" is produced inside the chute. It is also necessary to add, which the jets of water that are added through the pipe, do not occupy the total section of the pipe, in addition the chute is empty (it does not have water inside).

Hi,

 

I was going through the user forum looking for a different question and accidentally came across this thread. Looks like there is no notification sent to the email when someone mentions my name in a message. Anyways, this problem will require multiple carrier fields on the CFD side which we don't support currently with AcuSolve-EDEM coupling.

 

Thanks,

Ravi

Hello Ravi,
So you tell me that we can´t develop the behavior described in my post even having the mechatronic license?

to summarize, there is no solution?

Could we, maybe, simplify the system and the phenomenon to develop a coupled simulation? (DEM-CFD)
