Hi, wonder if anyone encounter this when they set up DPM droplet injection. The DPM particles will have a reverse flow phenomenon (the particles will flow upstream of flow, even though it is injected in a downstream position)

How are you defining the injection? Is there a velocity component that could cause this? Also, what body forces do you have in your model?

The injection can be pressure swirl or plain orifice. Think of a cylindrical duct with airflow flowing from left to right. There is a wall injection perpendicular to the wall and flow direction. The injected particles will flow to the left before making a u-turn to the right, hence why I described as reverse flow.
