Discharge coefficient of a classical venturi tube for measuring liquid helium flow

The hydrodynamics of liquid–liquid upflow through a venturimeter

“…Most of the researchers Huang et al, 2005) have used a flow pattern detector or void fraction meter in addition to a venturimeter for measurement of the total flow rate. There have also been some attempts (Katheder and Susser, 1989;Huang and Sciver, 1996) to predict the flow rate of two-phase helium flow.…”
