摘要
以机翼外翼翼盒作为研究对象,针对施工人员进入翼盒作业时的环境保障问题,设计通风方案并进行仿真分析.首先进行简化物理模型,建立数学模型,分析边界条件.然后采用计算流体力学软件Fluent对翼盒内气流速度、温度、甲醛浓度等进行模拟.根据仿真结果对各个通风方案的通风效果、制冷效果以及空气净化效果进行分析,最后设计进行实物通风实验对仿真结果进行验证.实验结果表明与仿真模拟的结果一致,验证了设计的机翼翼盒通风系统方案的可行性.
Abstract
Aiming at the problem of environmental protection when construction personnel enter the wing box,taking the outer wing box as the research object,different ventilation schemes were designed.At first,the simplified physical model,the mathematical model was established,and the boundary conditions were analyzed.Then the computational fluid mechanics software Fluent was used to simulate the airflow velocity,temperature,formaldehyde concentration and so on inside the wing box.Ventilation,refrigeration,and air purification of individual ventilation schemes were analyzed based on simulation results,and physical ventilation experiments were finally designed to verify the simulation results.Experimental results showed consistent with the results of simulation,confirming the feasibility of the designed wing box ventilation system proposed in this article.
