Particle size in Eulerian Multiphase Model.

Hello,
I am using a Eulerian-Eulerian Multiphase model to simulate the Oil separation from the Air. Any "clue / guidelines" to choose the Secondary phase Oil particle Diameter size, for Phase definition? (Volume fraction of Oil varies from 3 to 11 %) Thanks in advance. Guru. |

You can see the manual. I think you can select the oil as the secondary phase. However, in Eulerian-Eulerian Multiphase model , you only can set one diameter size, not a diameter size distribution.

you can use the udf! #include udf.h
DEFINE_PROFILE(particel_distribution,thread,index) { real x[ND_ND]; real y; cell_t c; begin_c_loop(c,thread) { C_CENTROID(x,c,thread); y=x[1]; F_PROFILE(c,thread,index)=1(exp(pow(y16,1.2))); } end_c_loop(c,thread) } |
