垂直円管内の沸騰を伴う流動の可視化実験 : 小質量速度,小加熱熱流束の場合

抄録

The purpose of the present paper is to understand how boiling two-phase flow behaves in a vertical circular tube for the case of small mass velocity and small heat flux. Flow visualization study was made to investigate the effects of the mass velocity and heat flux on boiling two-phase flow in the tube. It has been found that the flow pattern and/or flow pattern transition is influenced by the inner diameter of the tube, and that the height of the dry-out point depends on the mass velocity, heat flux and inner diameter of the tube.
