Research on the Shape of Oxidation Ditch Diversion Wall

Abstract:

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.
