An improved porous media model for simulating the flow–nets interaction

Physics of Fluids, Год журнала: 2024, Номер 36(2)

Опубликована: Фев. 1, 2024

This study presents an improved porous media model for simulating the interaction between fixed aquaculture nets and flow. The fluid motion is computed based on Reynolds time-averaged Navier–Stokes equations regular Eulerian mesh. simulates nets, where interface complex shapes of determined by continuous forced immersed boundary (IB) method. volume fraction defined embedded in coefficients porosity to set parameters at IB. Several cases validate model, including flow interactions with single net panel, gravity cage, offshore platform. Meanwhile, effects incoming velocity, attack angle, solidity, shape simulation are investigated. numerical can reasonably predict hydrodynamic a relative error less than 8%. Moreover, computational efficiency shaped significantly improved, maximum about 11.54 times.

Journal of Marine Science and Engineering, Год журнала: 2024, Номер 12(6), С. 972 - 972

Опубликована: Июнь 9, 2024

As nearshore aquaculture spaces become saturated, the development of fisheries for deep sea has an inevitable trend. This paper proposes innovative deep-sea platform that incorporates a vessel-shaped main structure and single-point mooring system. The potential flow theory Morison equation are utilized to calculate hydrodynamic loads on netting systems, respectively. deformation force in current simulated, accuracy analytical methods used is validated based experimental results. influences system characteristics analyzed. Optimization conducted under static dynamic conditions, considering various parameters, including line length, buoyancy buoys, mass sinkers. patterns changes motion response, tension, minimum touchdown length different parameters calculated results indicate have minimal impact response addition appropriate buoys or sinkers can reduce tension lines. Moreover, compared adding incorporating more effectively enhances overall safety stability
