i what to add particle particle collision to a solver, i was wondering how i would call it and where would i need to call collision.H
thanks in advance alan |

What's your case? And how are you planning to model the particle motion? Eulerian or Lagrangian approach?

lagrangian approach, i was looking at the user contribution icoLagrangianFoam and was just wondering how you would include collision model

Alan,
Nicolas Nordin implemented Peter O'Rourke's droplet collision model as a spray sub-model in OpenFOAM. O'Rourke's model presumes stochastic Lagrangian Particle tracking and uses kinetic theory to do an acceptance/rejection calculation of collisions. See: /home/foam/OpenFOAM/OpenFOAM-1.3/src/lagrangian/dieselSpray/spraySubModels/colli sionModel For particles, other than drops, you can re-use the code that calculates the incidence of collision and modify the part that calculates the outcome of collision. I have developed my own algorithms, but haven't written them into OpenFOAM. |

I am a Japanese student.
I am researching the collision of the droplets at the university, but the thesis and URL of the collision model are few in Japan. I cannot understand trajectory model and ORourke model. So, I want to read the thesis of the collision model. Could anyone teach me the thesis or URL of the trajectory model and the ORourke model? I'm sorry my bad English. |
