Metallic foams in liquid state, which is consisted of random packing of gas bubbles in a small amount of metal in liquid state with lots of gas/ liquid interfaces, are typical forms of soft materials. That is in non-equilibrium essentially. Drainage means that liquid flows inside a micro-channel of foams, which is one of primary factors to liquid foams’ stability. In this paper, we present a structural model of a single node with different liquid holdup by Surface Evolver（2.30）firstly. Then CFD (FLUENT) is used in computing the velocity field in a single node. The compute results suggest that average velocity and mass flow rate is satisfied with the correction of and the linear relationship between mass flow rate and pressure difference is satisfied with the correction of approximately. The research on Nodes’ function in foam drainage will give us more deep insight on foams’ stability and drainage.
