根据两流体同心环状流线性稳定性分析的结果，对微重力气／液两相流地面模拟实验所应遵循的相似准则进行了探讨，得到了一个新的重力无关性准则，即Bond数和环形区流体相的毛细数之比的绝对值不大于1．此外，微重力气／液两相流模拟实验还必须满足两个条件，即流量比和气相表观Weber数应与所模拟的流动中对应数值相等． |

In the present paper, the principle of similarity for two-phase flows at microgravity is studied based on the results of the linear stability analysis of the two-fluid concentric annular flow configuration. A new criterion of gravity-independence, namely the absolute value of the ratio between the Bond number and the capillary number of the phase flowing in the annulus is no more than one, is achieved. It is also pointed out that the flowrate ratio and the gas superficial Weber number must have the same values as their counterparts in the simulated flow in order to simulate correctly the behavior of two-phase flow at microgravity. |
