Hello!!
I am running DPM simulation using 2-D Axisymmetric, Multicomponent Model. I injec water-urea solution about 0.00038 kg/s and 380 parcels with 0.01 sec timestep. I found that every injected particles are evaporated!! the temperature and the residance time is enough to evaporate every particles No escaped, No aborted, only evaportaed. But when I see a 'mass flux report' , DPM Mass source is 0.000288 kg/s. There is a big diffence between the mass I injected and the mass evapored in the domain. I tried same simulation using a more dense mesh with double precision, the result is same. how can i fix this? |

Now, I am running same simulation on 3-dimensional mesh with same setting.
I found that the mass balance is correct. The mass of evarporated particles is same to what I setting on boundary condition. I think this problem is orruring at 2-dimensional axisymmetic. |
