摘要:

目前聚变堆设计中采用的T管氦冷偏滤器存在着钨瓦温度分布不均、局部区域出现材料超温等问题,为保证偏滤器的安全性与经济性,利用ANSYS-CFX软件对初始T管氦冷偏滤器单元模型进行热工水力分析,得到偏滤器单元各结构的温度分布以及冷却剂氦气的流速分布。通过对模型出口位置、壁面粗糙度以及冷却剂流量的优化,一方面优化氦气流速,降低压降以及提高结构温度均匀性,另一方面提高偏滤器单元的热交换效率,降低偏滤器单元最高温度,从而优化T管氦冷偏滤器单元的热工水力结果。

Abstract:

The current design of T-tube divertor in fusion reactor has problems such as uneven temperature distribution of tungsten tile and material overheating in local areas. In order to ensure the safety and economy of the divertor, the thermal hydraulic analysis of the initial T-tube helium cooled divertor unit model was carried out using the ANSYS CFX software, and the temperature distribution of each structure of the divertor unit and the flow velocity distribution of helium in the coolant were obtained. By optimizing the outlet position, wall roughness and coolant flow rate of the model, on one hand, optimize the helium flow rate, reduce the pressure drop and improve the structural temperature uniformity, on the other hand, improve the heat exchange efficiency of the divertor unit and reduce the maximum temperature of the divertor unit, so as to optimize the thermal hydraulic results of the T-tube helium cooled divertor unit.

Key words: Helium cooled divertor, T-tube unit, Thermal hydraulic optimization and analysis
