Effects of temperature fluctuation on PIV measurement of natural circulation flow field

Tsuji, Mitsuyo ; Aizawa, Kosuke ; Kobayashi, Jun ; Kurihara, Akikazu ; Miyake, Yasuhiro*

The particle image velocimetry (PIV) was measured in scaled-model water experiments simulating a natural circulation flow field in a sodium-cooled fast reactor vessel. The temperature fluctuation in the natural circulation flow field causes the distribution of the refractive index. Thus, the temperature fluctuation affects the uncertainty of the velocity in the PIV measurement. In this study, the authors evaluated the effects of the temperature fluctuation on the PIV measurement in the natural circulation flow field.
