| 摘 要： | 应用商业软件ANSYS CFX计算了等离子体热通量和液态锂流速对自由流动液态锂温度分布的影响。计算结果表明,导向槽中心附近液态锂温度较高,冷却水入口和出口对应位置液态锂温度最低。液态锂出口温度随着等离子体热通量的增大而线性升高,冷却水流速为1.5m·s-1,热通量分别为0.1MW·m-2和1MW·m-2时,液态锂在出口处对应的温度分别为255.3°C和458.6°C。增大液态锂流速,导向槽内液态锂的温度逐渐降低,但温度变化的幅度较小。计算结果对液态锂回路安全稳定运行提供了一定参考。

| Abstract: | Commercial software ANSYS CFX are used to calculate the effect of heat flux and liquid lithium velocity on temperature distribution of the free flow of liquid lithium. The calculated results show that the temperature of liquid lithium is higher near the center of guiding groove, the temperature of liquid lithium is lowest in the location corresponding to inlet and outlet of cooling water. The outlet temperature of liquid lithium rises linearly with the increase of plasma heat flux. When the velocity of cooling water is 1.5m·s−1, heat flux are 0.1MW·m−2 and 1MW·m−2 respectively, the corresponding temperature of liquid lithium at outlet are 255.3°C and 458.6°C. The temperature of liquid lithium within guiding groove dropped gradually with increase of velocity of liquid lithium, but the amplitude of temperature variation is smaller. |
