Quantitative measurement of void fraction distributions in gas-liquid two-phase flow by neutron radiography

  • 1. Dept. of Mechanical Engineering, Kobe Univ., Kobe (Japan)

Description

A quantitative measurement method by neutron radiography was proposed for two-dimensional void fraction measurement in two-phase flow. The uncertainty and the effects of the time averaging were analyzed for the void fraction measurement in two-phase flow by neutron radiography. It is concluded that the accuracy of the void fraction measurement by neutron radiography is enough for two-phase flow researches especially for annular and churn flows. This method was applied to the three-dimensional void fraction measurement of gas-liquid two-phase flow in a rod bundle with CT reconstruction. (orig.)
