As far as I know, the (D)DPM modelling does not take into account the volume of the discrete phase – only its mass and density are defined (which mathematically does result in some volume but the volume of the powder is not "added" to the slurry during injection.)<\/p>\n

Now please imagine the scenario below:<\/p>\n

a 100 litre container is to be filled up with a slurry. The slurry contains 80% VOLUMETRIC water and 20% powder. The powder is to be injected into the domain later. <\/p>\n

So, how much of the container should I initially (i.e. before injection) fill with water in my simulation? Should I fill ONLY 80% of the container with water, and add the discrete phase? If so, then this leaves us with only 80% of the container occupied with water and powder, while in reality the whole container is to be filled. Or should I FULLY fill the container with water initially regarless of the fact that, again, in reallity, only 80% of the container is occuppied with water?<\/p>\n","protected":false},"template":"","class_list":["post-165915","topic","type-topic","status-closed","hentry","topic-tag-ddpm","topic-tag-dpm","topic-tag-injection"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
