摘要
CFD验证和确认是气动计算可信度分析的基本活动。通过这类活动将产生大量数据资源。如何有效管理和利用这些数据资源是基准数据库要解决的主要问题。研究并提出了一种可行的共享基准数据库设计方案,重点强调数据库的管理、数据库的可用性、数据的可靠性评估、数据标准和开放的系统架构,目的是提供建立用于CFD验证和确认的气动共享基准数据库的一种示范,解决现有气动数据库普遍存在的缺乏协调性、连贯性和必要的交流等诸多问题。此外,简要介绍了近年来中国在气动计算可信度分析方面所做的努力。
CFD verification and validation （V＆V） are fundamental activities of credibility analysis for aerodynamic simulations. Through these activities, a large number of data resources will be generated. How to efficiently manage and utilize these treasures is the key problem for benchmark database. In this paper an operable design of open benchmark database is studied and proposed with emphasis on administration, availability, data reliably, unified data standards and open system architecture. The purpose is to provide a paradigm of aerodynamic open benchmark database for CFD V＆V, and to overcome some universal obstacles in current aerodynamic database such as lacks of coordination, continuity and necessary communication. Besides, some recent efforts of credibility analysis for aerodynamic simulations in China are briefly introduced.
