Figure 3. — Hagen–Poiseuille flow in an inclined cylinder. Relative error on the computed flow rate as a function of vessel diameter and lattice-Boltzmann (LB) relaxation time . For , the total error is kept below 3% even for cylinders with just three lattice sites across. These results confirm the suitability of the LB algorithm for the simulation of flow in sparse geometries and porous media. The lines are a guide to the eye and bear no physical meaning.
