> 中文摘要: 安全壳是核电工业中用于保护核反应堆运转的重要安全设备,对安全壳相关的测量数据或仿真数据进行可视化,有助于及时发现其中可能潜在的安全问题.根据安全壳的形状特征,提出一种基于圆柱坐标系的网格划分方法及物理量数据可视化表达方法.通过设定圆柱坐标系下的单一维度坐标,实现网格单元划分的横截面与纵剖面的直观显示.使用八叉树组织存储网格单元,有效地改善了存储性能,提升了网格单元查找速度.通过设定圆柱坐标系下的单个或多个维度坐标,实现了基于时间或空间变化的多种截线图、截面图的可视化显示.实验结果表明,该方法可实时显示安全壳的运转状况,有效地模拟安全壳运行的物理规律,确保核电站反应堆的安全.
Abstract:Containment is an important safety device for the protection of nuclear reactors. Visualization for measurement data or simulation data of the containment can help discover potential security issues. This paper introduces a mesh generation method and a physical data visualization method by leveraging cylindrical coordinates to represent the shape of the containment. By setting one-dimensional attribute of the cylindrical-coordinate system, the cross-section and longitudinal-section representations of mesh cells are illustrated. By using an Octree structure to store cells, the presented approach achieves good space performance and time performance. By setting one or more dimensional attributes, line and section representations for the physical data are obtained. Experimental results show that the proposed method can depict the running of the containment in real-time, simulate the physical laws of the containment effectively, and therefore ensure the safety of nuclear reactor.
