应用商业软件 CFX 计算了液态锂流速、热通量、冷却水的速度和温度对自由流动液态锂在热负荷作用下液态锂温度和水冷效率的影响.结果表明:液态锂温度随液态锂流速的增大而降低.热通量小于2MW·m-2时,水冷能够满足对液态锂温度控制的要求;在更大热通量作用下,水冷却显现出冷却能力不足.增大冷却水流速是降低液态锂温度、提高冷却效率的有效途径;冷却水温度对液态锂温度和冷却效率的影响较小.

Using commercial software CFX, the effect of velocity of liquid lithium, heat flux, velocity and temperature of water on temperature of the free flow liquid lithium and cooling efficiency of water under the action of thermal load was calculated. Results indicate that temperature of liquid lithium will decrease with the increase of velocity of liquid lithium. When heat flux is less than 2MW·m-2, water cooling can meet the requirements of the temperature control of liquid lithium, however, cooling capacity of water is insufficient when heat flux is much higher. Increasing the velocity of cooling water is the effective way to decrease temperature of liquid lithium and improve cooling efficiency. The temperature of water has a little impact on temperature of liquid lithium and cooling efficiency.
