Data Structure Design and Application of CFD Verification and Validation Database Platform

摘要:

计算流体动力学（CFD,computational fluid dynamics）验证与确认数据库平台用于存储和管理精细风洞试验、飞行试验、数值计算产生的标准算例数据。针对结构复杂、维度较高且参数不固定的CFD验证与确认标准算例数据，设计一种灵活的数据结构，动态存储不同标准算例的来流状态数据与结果数据，减少数据冗余，提高数据可扩展性。基于该数据结构完成标准算例数据质检与元数据管理设计，确保数据库平台能够精准、高效的为CFD软件可信度评价或相关研究提供数据服务。应用证明，验证与确认数据库平台实现了标准算例数据的有效管理和高效应用，为国家数值风洞工程和国内相关CFD软件的验证和确认提供了有力支撑。

Abstract:

The CFD verification and validation database platform stores and manages standard case data generated by fine wind tunnel tests, flight tests, and numerical calculations. The standard case data has the characteristics of complex structure, high dimension and variable parameters. A flexible data structure is designed to dynamically store the incoming state data and result data of different standard case. This design can reduce data redundancy and improve data scalability. Based on this data structure, the standard case data quality inspection and metadata management functions are designed to ensure that the database platform can accurately and efficiently provide data services for CFD software credibility evaluation or related research. The application proves that the verification and validation database platform has realized the effective management and efficient application of standard case data, and provided a strong support for the verification and validation of national numerical wind tunnel engineering and domestic relevant CFD software.
