TACR压力管与排管间辐射换热分析

Analysis on Radiation Heat Transfer between Pressure Tube and Calandria Tube of TACR

辐射换热是钍基先进CANDU型反应堆(TACR)压力管和排管间换热的主要途径。本文以灰体辐射模型和电网络分析方法为基础建立了TACR压力管和排管间辐射换热的计算模型,利用该模型计算了给定温度边界和热流密度边界的情况下,压力管和排管间的辐射换热能力。计算结果表明,该模型可以用于TACR压力管和排管间辐射换热能力的计算。

Heat radiation is the primary way for the heat transfer between pressure tube and calandria tube of TACR, and its accurate analysis is very important for design and safety analysis of TACR. A calculation model of radiation heat transfer between the pressure tube and calandria tube of TACR, which is based on grey body radiation model and electronic network method, has been established. The cases with temperature boundary condition and heat flux boundary condition are discussed, and the results prove that this model can be applied to the analysis of radiation heat transfer between the pressure tube and calandria tube.
