Abstract

The invention relates to a resonant jet experimental device and a method for conducting an optimization experiment through the resonant jet experimental device. The resonant jet experimental device is formed by detachably installing a shell, a fixing barrel and a jet device together, the shell is a barrel body with a shell bottom, a center hole is formed in the shell bottom, the jet device is fixed in the shell through the fixing barrel, and the fixing barrel is in threaded connection with the shell; the jet device is composed of an upper jet nozzle, a jet barrel and a lower jet nozzle in a detachable mode, the upper jet nozzle is arranged at one end of the jet barrel, the lower jet nozzle is arranged at the other end of the jet barrel, the lower jet nozzle is in threaded connection with the jet barrel, the fixing barrel abuts against the upper jet nozzle, the lower jet nozzle stretches out of the center hole of the shell, the upper jet nozzle is provided with an inverted circular truncated cone type gradual contracting inlet and a circular truncated cone type gradual expanding outlet, and the end face of the inlet end of the lower jet nozzle is tilted downwards. The resonant jet experimental device is detachable, especially, the jet device is detachable, lots of experiments can be performed by changing the type and size of the jet device so that strength of the hydraulic vibration effect can be observed, accordingly, jet devices of different types and sizes can be evaluated, and the optimal structure parameter of the resonant jet experimental device can be preferentially selected out.
