The Influence Study of Inlet System in Recirculating Aquaculture Tank on Velocity Distribution

摘要

In this paper, a three-dimensional numerical model was established byusing computational fluid dynamics to explore the improvement ofhydrodynamic conditions and the flow field characteristics in arectangular tank with arc angle. Design parameters of inlet system suchas the jet angle and the number of inlet holes (the total inlet arearemains constant) were studied on the velocity distribution uniformityin the aquaculture tank. The results indicate that the velocitydistribution uniformity in the tank is the best when the jet angle is 0°；the number of inlet holes has little effect on velocity distribution oftank when the total inlet area remains constant.
