Hydraulic Slide Valve Pressure Simulation and EDEM Sticking Analysis in Aviation
摘要
Abstract
To mitigate the impact of sticking in aviation hydraulic slide valves on flight safety,we adopt EDEM-Fluent coupling-Fluent simulates fluid flow while EDEM models contaminant particle motion and interactions-since traditional flow field analysis is insufficient.We adjust boundary parameters like opening to explore particle effects on pressure output and sticking evolution,and analyze particle distribution as well as transient flow area changes caused by particle accumulation.Regional particle accumulation correlates with particle size distribution,flow field jets,vortices and wall friction;sticking leads to pressure and mass flow rate oscillations.The coupled simulation reveals sticking mechanisms and provides technical support for health-oriented lifecycle green design of hydraulic slide valves.关键词
