I am not sure, actually i am not doing any real simulation using any method. It is more related to understanding the basics. I saw the conflict here, and i cannot find the answer for that. We are in...

It is a single phase flow. I would like to resemble the continuous scalar field 'C' by 'very small particles'. We can imagine the particle as 'fluid parcels'.
What is clear is how a advection...

Thanks and sorry for lots of questions. I hope it is the last one:
What we know so far:
1) The number of particles in some area per unit volume is more than other area.
2) the scalar field 'C' is...

I mean the number of particles in an specific volume size. For example, by a finite volume mesh descritization, if all mesh cells have the same volume size, the number of particles in the cells near...

I can imagine that the whole domain is filled with particles in the steady state. But is the volume fraction of particles near the wall is same as the volume fraction in the middle of the domain?
Or...

Thanks. But how the particles can go to the area in the domain where the streamline is nearly zero? assume we have a solid circle in the middle of the domain and we have a moderate Reynolds number...

Particles following the flow trajectory

Consider a simple 2D channel where the flow enters the domain from one side with the inlet velocity boundary condition with a constant value and it forms a boundary layer.

1) If i add many number...
