Particle diameter and particle flow rate not as specified
 
I am currently working on a simulation with a particle laden flow using the euler-lagrange-scheme with one way coupling. For the dispersed phase I am using air and solid particles. I specified a constant particle diameter of 0.1 mm and a constand particle flow rate of 10 particles per second. The particle density is set to a fixed value as well. However using all different kinds of injectors I get different particle diameters and different particle flow rates then what I specified. Changing the time step also changes the amount of particles my injector is injecting into my region.


At the moment I am lost for help and dont know what to change next. Any help is greatly appreciated
