摘      要：Fluid resonance in moonpool formed by twin boxes under wave actions is investigated by using a viscous numerical wave flume with ReNormalization Group(RNG)turbulent *** accuracy of the numerical model is validated by available experimental *** types of edge profiles,the sharp edge,concave edge and convex edge are *** simulations show that the normalized resonant amplitude in moonpool decreases with the decrease of moonpool opening or increase of incident wave *** increased reflection coefficients are the major reason for the phenomena,implying less wave energy is able to support the wave resonance in *** the increase of incident wave height,the energy coefficients increase for convex edges around resonant fre-quency,which are oppositely with those of sharp and concave *** flow patterns of the wave resonance in the vicinity of the moonpool entrance are also identified,which are mainly dependent on the edge profiles.
