| Research Abstract |
Development of measurement method using neutron radiography and conductivity probe, to investigate Pb-Bi two-phase flow. A simple algorithm using 4-sensor probe was derived to measure bubble velocity in a gas-liquid two-phase flow. Measurement error of bubble velocity and shape was estimated numerically and experimentally, assuming spherical and ellipsoidal bubble.
