초록
A numerical analysis of steady/unsteady flow applying cavitation model and moving mesh method was carried out in order to analyze performance of the control valve in a flight actuator system. The flow of the valve was assessed according to operation temperature and time. From this research, it was found that valve characteristics became stable at above a specific temperature and the cavitation affected performance of the valve. Response characteristics in position switching process were analyzed by modeling kinetic equation of the spool.
