2130 多点埋め込み式抵抗プローブによる液膜厚さ分布の計測に関する研究  [in Japanese] Studies on Thickness Profile Measurement of Liquid Film with Wall Mounted Multi-Points Resistance Probe  [in Japanese]

The measurement of liquid film thickness is essential to investigate liquid film structure in the two phase annular-mist flow and especially to establish the dry out mechanism of liquid film on fuel rod around spacer in the fuel assembly of BWR. The basic experiment is conducted to multi-points resistance probe to measure liquid film thickness profile in a rectangle tube or a triangle tube.
