Abstract

A mass transfer model for corrosion products (CPs) in a liquid metal cooling system has been developed. The spatial variations in CPs concentration are determined by integrating the source term of the mass transfer model with models for radial iron dissolution, precipitation, particle deposition, and erosion. The model has been validated and verified using experimental data from a lead-cool loop and air. Subsequently, it has been applied to analyze the multi-modular lead-bismuth eutectic (LBE) loop. The results reveal the CPs transfer rate, CPs concentration distribution, overall corrosion characteristics, and the impact of CPs mass transfer on corrosion behavior.

评估氯化石蜡转移对液态铅铋共晶冷却体系中腐蚀行为的影响

我们建立了液态金属冷却系统中腐蚀产物（CPs）的传质模型。通过将传质模型的源项与径向铁溶解、沉淀、颗粒沉积和侵蚀模型相结合，确定了 CPs 浓度的空间变化。该模型通过铅冷回路和空气中的实验数据进行了验证。随后，该模型被用于分析多模块铅铋共晶（LBE）回路。结果揭示了氯化铋的传输速率、氯化铋浓度分布、整体腐蚀特征以及氯化铋传质对腐蚀行为的影响。
