Abstract:A special study is carried out to analyze the wave theory selection in the simulation of Gravity cage. Airy theory and Fifth Order Stokes theory are applied in the numerical model to simulate the behavior of the float collar and fishing net which are the main parts of Gravity cage bearing most waved-induced forces. Comparisons between experimental and simulated results are made to analyze the effect of different wave theory applied on the simulation results. Such conclusion can be obtained that when the value of relative water depth is larger than 0.18, linear wave theory is appropriate to be applied to simulate the behavior of Gravity cage.
