Description
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 1.5 m·s-1, heat flux are 0.1 MW·m-2 and 1 MW·m-2 respectively, the corresponding temperature of liquid lithium at outlet are 255.3 ℃ and 458.6 ℃. 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. (authors)
