高温加熱面のミスト冷却に関する研究 : 低過熱度域の伝熱特性

抄録

In order to determine the heat transfer characteristics of mist cooling in the range of small degree of superheating, detailed experiments have been conducted on mist cooling heat transfer from a circular superheated surface. The experimental results indicate that the heat flux curve obtained is a function of parameters such as sprayed mass flow rate and degree of superheating, in relation to the boiling and evaporation behavior of the liquid film formed on the heated surface. The effects of size, velocity and temperature of spray droplets on heat flux are also clarified. The mechanism of mist cooling heat transfer is discussed and theoretical and experimental results are compared.
