1.Dirichlet Boundary condition: all variables except pressure are specified at upstream of the flow domain.
2.No-slip condition at the solid wall is applied for velocities.
3.”Wall-functions’ are applied to describe the turbulent flow properties in near wall regions.
4.Neumann Boundary Conditions are applied at the outlet to satisfy the mass conservation law.
5.The most important information for particle transport is the initial conditions and physical state of the paticles.
