Abstract :
Liquid nitrogen boiling two-phase flows in a metallic container and in a heat exchanger were visualized by real-time thermal neutron radiography at JRR-3M at the Japan Atomic Energy Research Institute and image processed by the Musashi dynamic image processing system. Boiling phenomena in a pool and boiling two-phase flow in an aluminum plate fin type heat exchanger were visualized. It was shown that neutron radiography was applicable to visualization of cryogenic boiling two-phase flow and the designs of cryogenic heat exchangers.
