Hey foamers:
I hope all of you have a nice weekend. I would like to inquire you the " Uturb" in the parcel, which is used in the DieselFoam. I read the source code, but it is sad that I didn't find where to solve the Uturb. Moreover, I also don't understand the function of the dispersionModel. Does it have some relation with the Uturb? Thanks and best wishes! |

Is there anybody know about the problem?
It is very small question, but it is very important. |

have you checked for instance
src/lagrangian/dieselSpray/spraySubModels/dispersionModel/stochasticDispersionRAS/stochasticDispersionRAS.C where Uturb is calculated. When the parcel properties are to be updated Uturb is simply added to to the gaseous velocity in src/lagrangian/dieselSpray/parcel/parcel.C as vector Up = sDB.UInterpolator().interpolate(position(), celli, facei) + Uturb(); so this will influence both drag and mass/heat transfer. |

Thanks for your reply, and I have checked that instance. However, I am not sure whether the dispersionModel has relation with the Uturb.
And I think if I don't need to use the Uturb. I think I only need to set up the option of " dispersionModel " off. Is it right? Thanks! |

setting it to off will result in Uturb = vector::zero. |
