湍流理想流体中汽泡的质量和能量
The mass and energy of a vapor bubble in a turbulent ideal fluid
摘要:
流体中气泡的质量可以看作是其中蒸汽的质量。气泡的自能定义为为了产生气泡而对流体压力所做的功。将水蒸气视为理想气体,得到了湍流理想流体中气泡的自能、质量和扰动波速度之间的关系。
英文摘要:
The mass of a bubble in a fluid can be taken as the mass of the vapor in it. The self-energy of the bubble is defined as the work performed against the pressure of the fluid in order to create the bubble. Taking the vapor to be an ideal gas the relationship between the self-energy, the mass of the bubble and the speed of the perturbation wave in a turbulent ideal fluid can be obtained.
