• The application of Random Matrix Theory to study the spectral statistics of bubble dynamics near a curved perforated plate in an infinite liquid domain is presented in this work. The simulation of bubble dynamics is conducted in the vicinity of a circular opening in the bilge. Empirical interpolation distribution is employed to quantify the chaoticity of the simulation results, while the boundary element method combined with RMT is utilized to evaluate the level spacing of different opening sizes and standoff distances. The objective of this study is to gain a deeper insight into the internal dynamics and to determine the presence of chaotic or regular behavior. The findings reveal that chaotic behavior emerges in the presence of jet formation in bubbles, while regular behavior dominates when jet formation is not observed. •The paper investigates the bubble dynamics by adopting simulation approaches and boundary element method.•The effects of the two key parameters including opening size and standoff distance, were numerically studied on the bubble dynamics near a curved perforated plate in an infinite liquid domain.•The results reveal the complexity of bubble dynamics and the capability of the boundary element method to predict the bubble dynamics.•The paper opens up new avenues to understand the chaos and regularity in the bubble dynamics.
