Hello everyone. I am trying to simulate a case using sprayFoam of OpenFOAM, where I am truing to limit the diameter of the injected parcels to a critical diameter. For example, if I inject parcels of diameter 4e-05, and if the heat transfer and phase change models are activated in the sprayCloudProperties dictionery, then the diameter of the parcels will gradually decrease and after some time become equal to 2e-05. After this, I want the diameter to remain constant at 2e-05 and don't want it to reduce further. How can I implement this above mentioned concept?
According to my knowledge, I know that size of a parcel decreases only due to heat transfer and evaporation (if we neglect breakup and collision models). So if I don't want diameter of parcels to decrease below 2e-05, I will have to switch off the heat transfer and evaporation models for those individual parcels which have reached 2e-05 size. How can I do this?
