摘要

摘要: 附件机匣作为航空发动机重要部件之一,其产热和散热的问题比较复杂.针对以往附件机匣相关研究只关注固体域的产热、散热分析,而对滑油散热作用不能充分考虑这一问题的现状,提出了基于流体仿真思想的稳态温度场分析方法.首先,通过分析附件机匣产热、散热问题的基本规律和特点,进一步采用k-ε湍流模型来模拟机匣内的情况,多相流模型模拟滑油,并且使用多参考坐标系模拟滑油在运动过程中的换热.最后,以某附件机匣作为具体应用案例,验证了方法的正确性和可行性,从而形成了一套行之有效的使用FLUENT软件对附件机匣进行稳态温度场仿真分析的模型和方法.研究的成果对于后续附件机匣的可靠性与寿命分析有重要支撑作用.

Abstract: Accessory gearbox is a major component of aero-engine, and the heat production and heat dissipation problems of accessory gearbox are complex. Previous studies have focused only on solid domains thermal analysis, however oil cooling effect has not been taken full account of. Aiming to complement this, a fluid simulation based on the steady-state temperature field thinking method of analysis was proposed. Firstly, basic rules and characteristics of the heat production and heat dissipation problems of the accessory gearbox were analyzed. Then we applied the k-ε turbulence model to simulation, applied the multiphase flow model to simulate the oil, and used multiple reference coordinate system to simulate heat transfer with gear rotation. Finally, the application of a specific case of accessory gearbox verified the correctness and feasibility of the method, which formed a set of effective models and methods using FLUENT software to simulate accessory gearbox's steady state temperature field. The result plays an important supporting role for subsequent research on accessory gearbox reliability and lifetime analysis.
