Stability of Free Surfaces in Single-Phase and Two-Phase Open Capillary Channel Flow in a Microgravity Environment

af Peter Canfield

Low Bond number open capillary channel flows have been shown to exhibit collapsing free surfaces when a critical flow rate is exceeded, a phenomenon that is referred to as choking. As shown in this work, the critical flow rate can be pre-determined with sufficient accuracy for the presented channel geometry when certain boundary conditions are known a priori. The presented model that describes the flow rate limitation of stable liquid flow through the open channel is examined and compared to num... (Læs mere)
