You can increase the number of particles by providing separately, different entry location, velocity and particle size. You can also inject the particle cloud/group. The mesh density will depend on the size of the smallest particle. To display the location of particle you can use any post-processing program. By using such program, you can plot time distribution at the outlet.

What comes to my mind from my past experiences with particle tracking, mesh size is determined by the smallest particle size, and mass injection or a number of the populations to be tracked is independent of the mesh dimensions.
