Diversion wall can improve bend flow patterns in an oxidation ditch. In this paper, a non-equal thickness diversion wall was proposed, and studied by numerical simulation method. The simulated velocity field of the new shape of oxidation ditch diversion wall was compared with that of the common shape diversion wall under the same boundary conditions, which shows that the new shape can better improve the bend flow patterns in an oxidation ditch, and reduce the size of the backflow area and increase the high-velocity region in the channel.

Boltzmann Method

The lattice Boltzmann formulation on unstructured grids (ULBE) is compared against semi-analytical solutions of non-Newtonian flows in straight channels, as well as with finite-element simulations in stenosed geometries. In all cases, satisfactory agreement is found, lending further credit to the ULBE method as a potentially useful method for the numerical simulation of small-scale hemodynamic flows, such as blood flow in capillaries and arterioles.
