Abstract:
A phase distribution parameter has been added to the one-dimensional
two-phase horizontal flow conservation equations. The phase distribution
parameter was incorporated into the conservation equations in an attempt to
add stability and remove correlation switching by incorporating gravity.
Determination of the phase distribution parameter requires an average void
fraction profile over the height of the flow geometry. Large amounts of void
fraction information are required to characterize the phase distribution over the
entire range of two-phase flows. Large amounts of void fraction information
can be efficiently gathered with real time neutron radiography. As a result of
the information gathered from the real time neutron radiography the phase
distribution parameter is produced for specific configurations under a wide
range of flow conditions.
