液体金属に対する濡れ性に乏しい構造材に沿ったボイド率挙動に関する研究が非常に少ない。本研究では、濡れ性や非濡れ性円筒周りの局所ボイド率分布が抵抗式プローブを用いて計測されたデータに基づき、非濡れ性単一円筒まわりのボイド率挙動が、衝突噴流,境界層流,分離流及び後流が現れるガスジェット-円筒系で定量的に議論される。

Little work on the void fraction behaviors along structural materials with poor-wettability for liquid metals has been performed. In the present study, void fraction behaviors around a single cylinder with non-wetting surface condition were quantitatively discussed by using a gas jet-cylinder system where the impinging jet flow, the boundary layer flow, the separation flow, and the wake flow appear. The characteristics in each flow field as well as the relationship between flow fields, which have not been quantitatively discussed so far, are obtained. The local void fraction around a single cylinder with wetting condition or non-wetting condition was measured by using resistivity probes.
