Abstract—A two-dimensional incompressible viscous flow numerical wave tank by a CIP (Constraint Interpolation Profile) method is established which has capability of handling the violent free-surface flow problems. Wave resonance at the narrow gap between twin caissons in close proximity is simulated. Firstly, a fixed twin floating-body model is set up in the work area of the numerical wave tank. Systematic simulations of regular waves acting on the twin floating bodies with narrow gap are carried out with a wide range of incident wave frequencies. By changing the gap width and the draft of the twin floating caissons, separately, the mean wave heights in the gaps are found to agree reasonably well with the experimental results and the previous numerical simulations, which demonstrate that the CIP-based viscous model has the accuracy to predict the wave interaction of twin caissons in close proximity.
