Dynamic Analysis of Longline Aquaculture Systems with a Coupled 3D Numerical Model

摘要

A 3D consistent mass-based model, cable model, is proposed to simulate the large deflection of the culture line structure. The 3D model couples the components of the entire aquaculture system. The simulations are performed with results compared with published data for suspended blades in both steady and oscillatory flow. Dynamics of a kelp longline system are studied for tidal currents scenarios. Results show that the longline tension follows water level to the peak at high tide and sensitive to water level in high tide. The non-parallel currents could enhance the tension as well as the deflection of the longline system.
