熱伝導体による流水中の冷却円管周りの凍結促進と抑制

抄録

Experimental and analytical studies of ice formation associated with heat conductor plates located around an isothermally cooled cylinder in crossflow are presented. The heat conductor plates are circular-fins having some clearance between a cooled cylinder and fins in the present study. The analytical results, assuming a quasi-steady-state condition, agree well with experimental data. It is proposed that the onset conditions, which describe whether the ice volume under a steady-state condition is greater or less than that without heat conductor plates, are defined by dimensionless radius, temperature and Reynolds number.
