Research on the Discharge Performance of Recirculating Aquaculture Seawater Pond Sewage Collection Device Based on CFD
To investigate the discharge performance of a sewage collection device used in a seawater pond recirculating aquaculture system,computational fluid dynamics(CFD)simulations were conducted to analyze its flow field.The study aimed to examine how particle release positions and sizes affect the device's efficiency in particle removal.The findings indicate that positioning particle release closer to the bottom of the diversion trough increases the depth of release and enhances particle removal at the device's bottom outlet.The average residence time of particles at this outlet varies with release depth,influenced by gravitational and flow dynam-ics.Smaller particles primarily exit through the upper outlet,resulting in shorter residence times.Conversely,larger particles demonstrate increased removal rates at the bottom outlet and generally shorter residence times.However,particles larger than 150 μm tend to exhibit longer residence times within the collection device.This research on sewage discharge performance offers valuable insights for developing sewage collection devices tai-lored for seawater pond recirculating aquaculture systems.
