Hi, I have a question about the units of DPM concentration when looking at particle flow results.
I understand that the units are in kg/m^3 however I am confused at what the mass means as I have not provided a mass for the particles?
Also, is there a way to show the particle results as number of particles per cubic metre on ANSYS fluent as that would be easier to understand.
Thanks sorry for all the questions I just need clarification on how to interpret my results :)March 8, 2022 at 11:45 amRobAnsys EmployeeThere is a mass flow associated with the injection, default is 1e-20kg/s. Given we track parcels, and that these can be different sizes, weights etc count per cell or per m3 isn't much use in most cases.
March 8, 2022 at 4:10 pmLyladSubscriberHi Rob, thank you so much for your reply so the weight part of the units (kg/m^3) is taken from the mass flow ?
So would it be more accurate if I calculate the mass flow rate for my particles ?
Sorry for all the questions :)
