RISA Computational Fluid Dynamics Approach for Modeling the Fluid–Structure Interaction of Offshore Aquaculture Cages and Waves
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Open ocean aquaculture cages became a promising alternative to traditional fish cage designs recently. The offshore environment implies larger loads on the structure and thus higher risk for fish loss. Floating rigid ...
