摘要
概述了计算流体力学(CFD)数值模拟和系统辨识的原理,详细阐述了基于CFD数值模拟的系统辨识"灰箱"建模方法的基本原理和实现步骤,对近几年该方法的应用案例进行分析,指出该建模方法存在的问题及发展方向。
The principle of CFD(computational fluid dynamics) simulation and system identification were summarized,including the presentation of "grey-box" modeling method and steps of CFD-based system identification;some applications in practice were analyzed to point out potential problems and its developing trends.
