Particle tracking in DPM
 

Hello friend,
I am modelling the impact of particle jet on the wall.Pls help me in getting the following information from the DPM model

1) I want to calculate the no of particles striking each face of the wall. I tried it by dividing the mass flow rate (mdot) in the DPM erosion model with the mass of individual particle, but the outcome would then be no. of particles striking per second, instead of no of particles.

2) Secondly, i want to calculate the impingement angle(alpha in DPM erosion model) of the particles upon striking the wall, but could not find the solution.

Please help me in retrieving these quantities.
