Interfacial fluid mixing driven by a shock wave is a common phenomenon that occurs frequently in basic science research and in a variety of *** this work,shock-tube experiments on the developments of two-dimensional tri-mode interfaces accelerated by a convergent shock wave are *** sets of different combinations in the value of phase and that of amplitude in a tri-mode perturbed interface are studied to evaluate the effect of mode coupling on the amplitude growths of the basic *** qualitative results show that the phase combination obviously affects the interface morphologies and flow *** alternation of each mode amplitude does not affect the major flow features,such as the number and arrangement of the bubbles and spikes,but affects the local interface *** upon the phase combination,the mode amplitude growth is either promoted or suppressed by mode coupling relative to the single-mode *** considering the feedbacks from both the first-order and second-order mode couplings,the mode amplitude growth can be qualitatively *** to dual-mode interface,mode coupling occurs earlier in tri-mode *** the sets of parameters we studied,the effect of initial phase on the amplitude growth is greater and occurs earlier for the mode with low mode *** addition,the amplitude development of mode with high mode number is more affected by initial amplitudes of basic modes than that of mode with low mode *** introduction of the third mode affects the amplitude growths of original two modes,but has little effect on the final mixing width ***,a theoretical model is proposed to predict the amplitude growth of each basic mode.
