The Theory of Pulsating Flow in Conical Nozzles [PDF]
Journal of Applied Mechanics, 1963 A knowledge of the dynamic characteristics of nozzles and orifices is important in many control and stability analyses of engineering devices. It is usual to assume that the instantaneous flowrate, for a given set of inlet conditions and outlet pressure, is the same as the nontransient value for the same operating conditions.
