Dear All,
I am simulating the deposition/ accretion of the small particle of the nozzle wall. I have stuck this problem a month, I have worked >10 hrs a day , somebody please help me.
First, I have read papers and understand the force and mechanism of deposition.
- Turbophoresis, Drag, Diffusion and Lift are main forces of particle deposition
Therefore, I have tried Eulerian(Granular) because i am sure that once the particle deposit. Particles can block main flow (water).
Unfortunately, the granular model makes particle attach the wall and slide slowly along the nozzle wall. It can not deposit.
(Question 1: Do you think my setup is wrong or Granular is not able to do this?)
Therefore, I am gonna try DPM, but I am not sure that "Accretion in DPM" can block main phase (water).
In the other word,
Question 2 :Can "Accretion in DPM" enough to cause clogging of the main phase(Water)?
Best Regards,
Yannapol S.
DPM will not work because when the particle hits the wall it is recorded and destroyed there can be no buildup of particles stuck to the wall that will change the flow characteristics. Try looking up lammps coupled with fluent i think this may solve your problem
I suggest you use fluent for continuous flow field prediction and then develop your own model for accretion. Please look at papers from Laszlo et al, in which they have tackled ice deposition problem on cables using the above mentioned methodology.
Dear Prof. Mishra, could you please kindly give us more detailed reference for the paper by Laszlo et al?
I am working on very similar problems using DPM.
you can use DPM for sure for deposition analysis in Ansys Fluent.
