Résumé

Liquid, vapor and non-condensable gas were visualized by neutron radiography. The flow of heat and mass in the helium loaded isooctane heat pipe was evaluated by thermal characteristics. The falling liquid film was visualized. The evaluation was done for heat and mass transfer of liquid film cooling.
