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.
