ITER液态锂铅回路鼓泡柱中提取氚的理论计算

Theoretical Calculation of Tritium Extraction From Liquid LiPb Loop by Bubble Columns for ITER

建立了1个描述ITER液态锂铅回路鼓泡提取器复杂的流体动力学的数学模型。模型中的等式无量纲,有合适的边界条件,依据正交搭配完成模拟计算。为更好地理解不同参数对鼓泡器性能的影响,引入许多假设,并将提取效率作为过程参数进行分析与计算。在此基础上提出了鼓泡柱提取系统的初步设计参数。

A mathematical model describing the complex fluid-dynamics of a bubble extractor from liquid LiPb loop for ITER was presented. The model equations were made dimensionless and, together with the proper boundary conditions, numerically solved by the orthogonal collocation technique. In order to better understand the role played by the different parameters in determining the performance of a bubble column, many suitable hypotheses were introduced. A parametric analysis of the extraction efficiency for a bubble column as a function of the process parameters was carried out and, on this basis, the design of a bubble extractor system was proposed.
