摘要:Based on finite volume method, the Reynolds number of fluid affecting solid-liquid two phase deposition on the outer surface of tubes has been predicted. A 3D geometric model of fluid flow cross tube bundles is established. The particle trajectory was tracked by Euler - Lagrange model. The results show that: different Reynolds number of fluid impact dynamic pressure which is consistent with the distribution of fouling deposition. That is to say, dynamic pressure can be treated as indicator when monitor the fouling deposition on the surface of tube bundle. The deposition rate of particles is positively correlated with dynamic pressure. In addition, based on this geometry model, with the increment of Reynolds number, average accretion rate tend to stabilize to, rather than increase indefinitely. The location of the most serious accretion rate is always on the joint between the pipe and the shell, especially, on the surface of windward.
