Abstract :
We visualized the working fluid behavior in a bent thermosyphon by a neutron radiography and analyzed it quantitatively with an image processing technique. Working fluid velocity was evaluated by the two-point correlation function and also the spatio-temporal correlation was calculated, which led to a clarification of the pass route of working fluid in the thermosyphon. The probability density function of the void fraction was calculated.
