I created a single-point injection as your recommendation. But, I got zero film stripping rate and film DPM mass source rate for the default settings in the particle stripping model. I changed critical shear stress from 100 to 90, 80, but got the same results(no striping and DPM source rate). Why is this happening?
When I used UDF entrainment correlation and created an injection from the wall by DEFINE_DPM_INJECTION_INIT macros, I got entrainment rate only. I got DPM mass source rate only when I created a second injection under DPM at the inlet and injected a fraction of liquid as droplets. What might be the reason for getting DPM mass source only when I have inlet injection and no DPM mass source for other cases?
