Abstract: | |
The internal flow field of a square container and a circular container was simulated by finite element software. The mixing result of fluid in the container and the influence on growth of the flocs during coagulation mixing were analyzed from the following four aspects: average turbulent dissipation rate, average speed, average turbulent kinetic energy and the scale of micro vortex. The result shows that the distribution of velocity field, turbulent kinetic energy field and turbulent dissipation energy field is more balanced in square container and leads to the formation of more λ scale of micro vortex. The hydrodynamic conditions are more favorable for the growth of the flocs. |
