摘要
为了全面获得飞行器发动机舱内的电子部件的温度分布,利用有限体积法,采用块结构化网格以及非结构化网格,建立了飞行器发动机舱的有限元模型;应用整体求解耦合问题的有效方法,对此发动机舱内外流场与温度场进行了三维的数值模拟;并对此发动机舱内的温度分布进行了重点数值仿真与分析,而且得出了飞行速度、环境温度等因素的变化对部件温度的影响关系。该模拟结果为发动机舱布局设计提供了参考价值,具有重要的现实意义。
In order to comprehensively obtain the temperature distribution of the electronic parts in the aircraft engine cabin, a finite elements model of the engine cabin is created using the block - structured and unstructured grids by the finite volume method. The flow field and temperature field inside and outside the engine cabin are numerically simulated by an effective method for solving integrated coupling problems. The heat transfer in this engine cabin is simulated and analyzed emphatically, and also, the influences of the changing of the flying speed, the environment temperature and so forth on the parts temperature are obtained. This simulation result provides a reference to the compartment design for the engine cabin, and is of great practical significance.
