Abstract

In view of the characteristics of the numerical simulation results of the nuclear reactor core, including the regular structures, multiple geometry duplications, large-scale grids, and the demand for refined expression of calculation results, a mesh generation method based on Delaunay triangulation was used to solve the restructuring and visualizing problem of core three-dimensional (3D) data fields. In this work, data processing and visualization of the three-dimensional refined calculation of the core were accomplished, using the triangular mesh model, hash matching algorithm, 3D visualization technology, etc. Descriptions are also given for key issues such as Delaunay triangular mesh construction, the geometric model of the reactor core, and 3D data field mapping in this work. The application results showed that the 3D physical field data, such as core power and temperature, can be accurately and efficiently displayed using the visualization technology and solution. In addition, the efficiency of design and analysis in nuclear engineering activities can also be improved significantly.
