As the method of measuring bubble flow from cool seeps on seafloor using acoustic transmission needs the media of homogeneity of acoustic impedance
the way of quaternary crushing bubbles is proposed and the biphase media of bubble-seawater homogenization device is designed. It includes two parts: bubble collapse and uniform distribution. The function of the biphase media of bubble-seawater homogenization device is that it can break big bubbles into small bubbles and let the small bubbles distribute evenly. The results of experiment show that the biphase media of bubble-seawater homogenization device can break the diameter of bubbles greater than 15 mm into 4 ~ 5 mm and distribute them uniformly. The rising velocity of bubble is 0.3~0.4 m/s
which can satisfy the requirement of the method of measuring bubble flow from cool seeps on seafloor using acoustic transmission.
