Figure 2.
Numerical solutions showing absolute dimensionless velocity. (a) Shows the microscale cell problem, (b) the numerical solution with the geometrically derived Beavers and Joseph boundary condition, (c) the full numerical solution with the aggregate structure taken into account, (d) shows the solution for an aggregate with a solid core and (e) shows the solution for an aggregate with a hollow core, (f) shows the solution in the boundary layer with velocity streamlines and (g) shows the full numerical solution for the square aggregate geometry.
