I am using DPM and EWF models to simulate annular flow in a tube. Here F_EFILM_DPM_MASS_SRC(f,t) command is used to calculate DPM mass source on liquid film. From the plot below I see a large fluctuation in deposition mass flux, especially for high air velocity. What might be the reason for this large fluctuation? Is it a normal case? Although entrainment flux showed a smooth line.
I am dividing F_EFILM_DPM_MASS_SRC(f,t) by area_face to get mass flux.

I am not sure why you are using UDF to access something which is available already in the variables: there you can access stripped mass and DPM mass source.
How are you quantifying the entrained mass: is it the stripped mass in your case?

Can you associate the plot with the events where DPM particles are hitting the wall film and getting absorbed there? If yes: that is the reason.
