为研究航空附件壳体冲洗时出口流速不能有效测量的问题,提出了一种航空附件产品壳体流体域的出口流速的预测方法与手段,并通过预测的结果对工艺进行优化.借助FLUENT仿真工具,通过建立壳体的流体域模型、网格模型,运用有限元的仿真计算方法分析评价现有冲洗工艺的优劣,在仿真的计算结果上得到流体域的出口的流速、云图、流线图等数据,预测调节器壳体出口流速的大小,例如初始仿真时,出口2、3、9 的流量很低,甚至还存在负压,流量分别为0.0017 kg/s、0.00002 kg/s、0.02 kg/s,通过封堵等其他出口的手段,将出口2、3、9 的流速分别提升至78 m/s、25 m/s、423.3 m/s,极大地改善了出口流体的状况.此方法能够对制造过程中合理制定冲洗工艺提供有效的帮助.研究将为航空燃油附件壳体的工程设计以及制造过程中冲洗工艺方法的制定提供理论支撑,其他涉及需进行冲洗工艺的制造过程领域也都具有较强的借鉴意义,研究具有较强的应用推广价值.
Simulation analysis and optimization of regulator shell washing process based on FLUENT
In order to study the problem that the outlet velocity cannot be measured effectively when the aero-accessory shell is washed,a method for the prediction of the outlet velocity in the fluid domain of the aero-accessory shell is proposed,and the process is optimized by the prediction results.By using the simulation tool FLUENT,the fluid domain model and mesh model of the shell are established,and the advantages and disadvantages of the existing washing process are analyzed and e-valuated by using the finite element simulation method.The flow velocity,cloud chart and flow diagram of the outlet of the fluid domain are obtained from the simulation results,and the outlet velocity of the regulator shell is predicted.During the in-itial simulation,the flow rate of outlet 2,3 and 9 is very low,and there is even negative pressure.The flow rate of outlet 2,3 and 9 is 0.0017 kg/s,0.00002 kg/s,and 0.02 kg/s,respectively.Through plugging other outlets,the flow rate of outlet 2,3 and 9 increased to 78 m/s,25 m/s,and 423.3 m/s,respectively,greatly improving the condition of the outlet fluid.This method has provided effective help for the washing process.The research has provided theoretical support for the engineering design of jet fuel accessory shell and the formulation of washing process in the manufacturing process,as well as reference for other manufacturing processes involving washing process.
