摘要: 运用FLUENT软件,使用欧拉两相流流动传热模型,对注气与不注气铅铋流体的速度场与温度场进行模拟,得到计算段不同轴向位置上的径向速度分布曲线与温度分布曲线。结果表明:气体存在或不存在的情况下,计算段的速度分布与温度分布都呈现很好的对称性;在注气的情况下,铅铋流体的温升比较大,即注气有利于铅铋流体在计算段的传热。Abstract: On the basis of two-phase flow and the heat transfer theory, the velocity and temperature of the lead-bismuth was calculated with gas-injection or without gas-injection by FLUENT code, in the calculation segment. The radial velocity profiles and temperature profiles were acquired at different cross section. Analysis results show that: no matter the air is existence or not, the velocity distribution and the temperature distribution have a good symmetry. Temperature rise of the lead-bismuth liquid with gas injected is larger than without air. It is shown that the gas-injection is good for lead-bismuth liquid heat transfer at the calculation segment.
