      I am using DPM surface injection model with coal as a fuel. It is carried by CO2. My model has converging inlet duct which ends at the burner main body. But when I view my DPM concentration contour I see the lower concentration region inside the inlet duct. What could be the problem regarding the variation in the dpm concentration inside the inlet?


      Thank You

      Please post some images along with a screen shot of the injection panel.

      If we observe properly we can see there are some regions with lower concentration? What might be the reason?

      Can you also plot particle trajectories?

      Please can you plot the particle tracks on the same view as the source term contour?

      In the rosin rammler distribution, surface injection, I entered the mass flow rate of particle, but in the velocity magnitude option should I enter the velocity of particle or should I enter the velocity of a coal carrier which has different mass flow rate and hence different velocity?
