CFD技术在航空发动机空气系统设计中的应用

摘要

The design technologies of secondary air system were intruoduced according to functions and design characteristics of the the secondary air system.Take several typical aeroengine structure for example,the flow characteristic and the fluid temperature are analysed using the commercial CFD software.It shows that the CFD is beneficial supplement for the current analysis technology and important tools to the aeroengine secondary air system fine design.The simulation result is instructive for the engineering design.%结合航空发动机空气系统的功能和设计特点,介绍了空气系统的设计分析技术现状;以2种发动机典型结构为例,采用商用CFD软件完成了流动与换热特性分析。CFD技术是现有分析技术的有益补充,是空气系统设计分析技术精细设计的重要工具,其数值模拟结果对工程设计具有指导意义。
