强流氘氚中子发生器可用于模拟聚变堆中子环境,对于开展聚变堆包层材料相关实验研究具有重要意义.本文提出了一种用于1012n·s 1量级氘氚中子发生器HINEG(high intensity neutron generator)的旋转氚靶系统设计方案,并对其技术难点和强化传热方法进行了介绍.为考查该氚靶系统的传热特性,利用Computational Fluid Dynamics方法对冷却水层厚度、冷却水流速和氚靶系统旋转速度对靶面冷却的影响进行了分析,并对不同热功率密度下靶面的传热过程进行了研究.结果显示,大的水层厚度、大的冷却水流速和高的靶系统旋转速度有利于靶面的冷却,但水层厚度和水流速的变化对靶面传热影响较小.一定条件下靶面所承受的热功率密度不能超过某个限值.
The strong deuterium tritium neutron generator can be used to simulate the fusion reactor neutron environment, which is of great significance for carrying out experimental research on the fusion reactor cladding material.In this paper, a new deuterium tritium neutron generator HINEG (high intensity neutron generator) is introduced, and its technical difficulties and heat transfer enhancement methods are introduced.In order to investigate the heat transfer characteristics of this tritium target system, Computational Fluid Dynamics method is used to calculate the cooling water layer thickness , Cooling water flow rate and tritium target system rotation speed on the target surface cooling were studied.The heat transfer process of target surface under different thermal power density was studied.The results show that the thickness of large water layer, large cooling water However, the change of water layer thickness and water velocity have little effect on the heat transfer of the target surface, and the thermal power density of the target surface under certain conditions can not exceed a certain limit .
