摘要
在ITER装置正常运行时,杜瓦内外温度不均,有一定的温度分布。考虑热辐射对杜瓦温度分布的影响,建立了用于辐射换热分析的杜瓦数值模拟模型,运用CFD软件Fluent对其进行数值模拟计算,得到杜瓦的温度分布,为后续的热应力分析提供了依据和参考。
Considering the impact of thermal radiation on dewar temperature distribution, the paper established the numerical model of dewar for radiation heat transfer analysis, and carried out the numerical simulation by CFD software Fluent. The temperature distribution of the dewar was obtained, which could provide a basis for the subsequent thermal stress analysis.
