摘要

针对海底冷泉天然气渗漏流量声波测量需要介质声阻抗均匀的要求，提出了气泡四元破碎方法，设计了一种气泡-海水两相介质均匀化装置.气泡-海水两相介质均匀化装置的功能包括两个部分：气泡破碎和气泡空间分布均匀化，其作用先将大气泡破碎成小气泡，然后再对小气泡的空间分布均匀化.实验结果表明：气泡-海水两相介质均匀化装置能够将直径大于15 mm的气泡破碎为当量直径为4～5 mm且空间分布均匀；另外气泡的流速基本在0.3～0.4 m/s内；达到天然气渗漏流量声波测量的要求.

Abstract

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.
