Hello guys,
i'm trying to simulate particles behavior and their deposition in lung, for this purpose i'm using population balance model and i'm facing with some difficulties in extracting results. my geometry has a velocity inlet, pressure outlet, and lung's wall as boundary conditions. particles are considered to be water and the main phase is air and i'm using the eulerian method. in each time step a specific volume fraction of particles (water) are injected to the domain from the inlet. one of the problems is that the fluent doesn't show the "moment 0" on the lung's wall properly (or better to say it doesn't show the number of particles deposited on the lung's wall in each time step properly).when i see the contours for "moment 0" it seems that after two time steps the particles are completely removed from the domain and new particles are injected from the inlet and the same thing happens to these new particles after another two time steps!! . i will be gratefull if some one help me with this problem. tnx. |
