使用水中的氧分子的行为的例子来分析注入液体中的气体的演化，其中气体分子的气泡通过气体分子附着到气泡而缓慢生长，然后气泡缔合并最终流动到液-气界面并进入气相。 两种方法被认为是在液体中的气体注入，插入单个分子和通过气体渗透通过多孔材料的小气泡的注射。分析了水中氧气泡的行为和生长过程。随后，这些生长的气泡上浮并消失，或者由于液体的湍流运动而到达水边界。 它示出，微米尺寸的气泡在水容器的各个区域中的尺寸分布函数的测量允许一个建立在气泡生长理论的基础上的流动电流线。气相中、气泡中和与溶剂结合的分子能量示意图
Evolution of a gas injected in a liquid is analyzed using the example of the behavior of oxygen molecules in water in which bubbles of gas molecules grow slowly by attachment of gas molecules to bubbles, the bubbles then associate and finally flow up to the liquid–gas interface and pass into the gas phase. Two methods are considered for gas injection in a liquid, insertion of individual molecules and injection of small gas bubbles via gas penetration through a porous material. The behavior of oxygen bubbles in water and growth of those bubbles is analyzed. Subsequently, these grown bubbles float up and disappear, or reach the water boundary as a result of turbulent motion of the liquid. It is shown that measurement of the size distribution function of micron-size bubbles in various regions of the water container allows one to establish the flow current lines on the basis of the theory of bubble growth.
