Abstract:
The structural parameters of a novel inclined plate micro?vortex flocculation tank were optimized through computational fluid dynamics (CFD) simulation. Utilizing the vortex scale as a criterion, the flow field and flow state under different structural parameters were investigated based on fundamental hydraulic indexes such as velocity, turbulent kinetic energy, and turbulent dissipation rate. This approach aimed to optimize hydraulic conditions and enhance flocculation efficiency. Subsequently, particle image velocimetry (PIV) and a pilot test were employed to validate the simulation results and ascertain the optimal operating parameters. The vortex scale served as an effective indicator for assessing the performance of micro-vortex flocculation tank. The particle image velocimetry technique and pilot test results validated the optimal structural parameters obtained through optimization of the internal flow field in the novel inclined plate micro-vortex flocculation tank.
