N. Takenaka et al., APPLICATION OF NEUTRON RADIOGRAPHY TO VISUALIZATION OF CRYOGENIC FLUID BOILING 2-PHASE FLOWS, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 377(1), 1996, pp. 174-176
Liquid nitrogen boiling two-phase Rows in a metallic container and in
a heat exchanger were visualized by real-time thermal neutron radiogra
phy at JRR-3M at the Sapan Atomic Energy Research Institute and image
processed by the Musashi dynamic image processing system. Boiling phen
omena in a pool and boiling two-phase flow in an aluminum plate fin ty
pe heat exchanger were visualized. It was shown that neutron radiograp
hy was applicable to visualization of cryogenic boiling two-phase flow
and the designs of cryogenic heal exchanges.
