Determining the discharge coefficient of a spool valve

Proceedings of the 2000 American Control Conference. ACC (IEEE Cat. No.00CH36334), 2000
Various mathematical models and experimental methods have been developed for finding the effective orifice area in spool valves. The orifice equation for turbulent flow is often applied to spool valves to determine the volumetric flow rate of the fluid passing through the spool valve.

Discharge coefficient and loss coefficient

2022
The article deals with natural ventilation in air vents of the chimney type by applying the principle of balance of mechanical energy. The connection between the concept of discharge coefficient and the loss coefficient of duct flow is introduced. Control volume treatments have important roles. Two simple application examples are given.
