dc.description.abstractIn this study, the mechanical behavior under highest thermal conditions and flow characteristics of the hydraulic fluid of the servo-characterized proportional valve, which is one of the indispensable components of the aviation industry and used for hydraulic flow control, were investigated numerically. In the simulations, 50, 75 and 100 °C were selected as temperatures, and 0.2 mm, 0.6 mm and 1.2 mm spool stroke openings were used for hydrodynamic flow. Simulations were carried out for a pressure difference of 35 bar. As a result of the analysis, it was observed that there was no restriction in the movement of the spool-sleeve structure for a temperature of 75°C, excessive friction occurred in the spool-sleeve structure at 100°C and the movement was restricted. In addition, it can be said that hydraulic turbulences are effective in dispersing polluting particulate matter for all three spool strokes at a pressure difference of 35 bar.en_US
