Data for: A Coupled POD-Kriging Approach for the Analysis of a Multi-Stream Heat Exchanger

The data is the results obtained from the POD reconstruction of the field of fluid flow and heat transfer in a three stream plate-fin heat exchanger as explained in the parent paper. They consist of 8 Binary data files each for one case, and each has four sections for three fluid streams and a solid body as shown on the Fig. 1. The solution has been based on unstructured grids so each section has two parts: the nodal data and the connectivity. The files are constructed for the post-processing by Tecplot software.本数据集为按照父论文中所述方法，对三股流体板式翅片换热器内流动与传热场开展本征正交分解（Proper Orthogonal Decomposition，POD）重构后得到的结果。数据集包含8个二进制数据文件，分别对应一组工况；每个文件包含四个数据段，分别对应三股流体流道与固体域，如图1所示。由于本次求解采用非结构化网格，因此每个数据段均包含两部分内容：节点数据与单元连接信息。本数据集文件专为Tecplot软件的后处理流程所构建。
