深水海洋气泡流的动力学模型

STUDY OF THE DYNAMICS OF GAS BUBBLES IN THE ABYSSAL PLUMES IN THE WATER AREAS OF OIL AND GAS FIELDS

介绍了深水条件下海洋气泡流的动力学模型,阐述了天然气水合物在天然气从深海到大气的传输过程中的重要作用。被天然气水合物包裹的气泡的动力学模型是在普通气泡模型的基础之上,引入一个参数值,通过模型模拟得到的数据确定的,可以用来描述水合物外层对气体分子和水分子扩散的抑制作用。

In this paper the result of study of dynamics of gas bubbles in deepwater plumes is stated, and the important function of gas hydrate on the transmission of gas bubbles from deepwater to the air is also introduced. This methodology allows to find the values of parameters that define the intensity of simulated process by systematically variating their values until a maximal approach of developed mathematical model on the base of the mathematical model of floating up and dissolution of routine gas bubbles. The inhibiting effect of the methane hydrate formated on the surface of bubble can be depicted by this process.
