The blue-green algae suction device is a kind of equipment using hydrodynamic forces to salvage bloom blue-green algae.Through numerical experiments,its hydraulic performance can be tested and the suction and collection effect of algae rich water can be evaluated.Using computational fluid dynamics(CFD)technology and numerical simulation methods,the internal flow of the blue-green algae suction head was calculated and analyzed.The overall flow characteristics inside the algal suction device,flow conditions at different cross-sections,internal flow head loss,and flow uniformity at different flow sections were obtained under design flow conditions and high flow conditions.Through numerical experiments,it has been verified that the overall flow of the blue-green algae suction device is basically undisturbed,without obvious turbulent flow patterns such as vortices and backflows.The internal flow performance is good,and the efficiency of extracting blue-green algae water is high.
