| Zusammenfassung: | The invention discloses a sleeve regulating valve resistance coefficient estimation method and estimation system considering cavitation influence. According to the calculation method, numerical simulation is carried out on the sleeve regulating valve to obtain a one-way flow resistance coefficient and a two-phase flow resistance coefficient under different valve front and back pressure difference values and different valve relative opening values, and the one-way flow resistance coefficient and the two-phase flow resistance coefficient serve as fitting data to fit a sleeve regulating valve resistance coefficient conversion formula; and obtaining a conversion model for calculating the resistance coefficient of the two-phase flow according to the resistance coefficient of the single-phase flow. According to the method, the relation between the single-phase flow resistance coefficient and the two-phase flow resistance coefficient is established by analyzing the influence of cavitation on the valve resistance coe |
