This paper describes a study of two-phase gas-liquid vertical
annular climbing film flow. Using a high speed Fastax movie camera,
motion was slowed sufficiently to facilitate detailed analysis of the
climbing film structure, based on single frame projections. The
dynamic characteristics of the liquid film could likewise be obtained,
though...
The effects of mass flow rate and subchannel configuration on
the turbulent interchange between adjacent subchannel in simulated
rod bundle were investigated.
The simulated rod bundle was made by arranging seven 1.913 cm
diameter acrylic plastic rods in an equilateral triangular pattern in a
tube 8.89 cm inside diameter.

Momentum transfer in climbing-film flow in an annular duct was
investigated. Air and various liquids, with a wide range of viscosities
and surface tensions, were investigated. The two phases flowed co-currently
upward, the liquid climbing as a thin film on the inner wail
while the outer wall remained dry.
The...
