I am getting the Film DPM Mass Source like below image. But, I am expecting a continuous increasing trend curve from inlet of the tube to outlet. As same heat flux is applied at the wall ,the dpm mass source should have an increasing trend towards outlet. Here I am getting some spikes of same length only.
What might be the reason of getting some spikes only? I am using Discrete Phase Model and Eulerian Wall Film Model to simulate annular flow in a pipe
