•Growth, propagation, merging and detachment of interface wave was observed.•Interface wave was proved to grow exponentially in axial direction.•Pressure oscillation of supersonic steam jet condensation was induced by interface wave.•A correlation for dominant frequency was proposed based on interfa...
