Effects of variable porosity net on flow field inside deep-sea aquaculture cage

Abstract This paper focuses on the effect of porosity nets flow field inside deep-sea aquaculture cage. Based CFD method, 2D fields and surrounding cage from different views are simulated. The effects certain net variable with configurations fishability area, efficiency benefit investigated. results showed that suitable in vertical direction can increase area change be conducive to improving fish aquaculture. In horizontal direction, increasing parallel incoming improve water exchange capacity. beneficial benefit. this guide for selection cages.
