摘　　要：Vortex diode,as an important component in power fluidics,has been used in nuclear reprocessing engineering where it is desirable to avoid pumps with moving parts.The performance of the fluidic system depends on the matched design parameters of vortex diodes and the supporting facilities.However,no clear guidelines for design and optimization of vortex diodes system are available.Therefore,we carried out detailed experimental study on hydraulic characteristics of the vortex diodes system with changeable parameters to evolve such guidelines.The study covered a wide range of a vortex diode and vortex diodes system.The variation of averaged discharge and volumetric efficiency in respect to air supply pressure,liquid level of water tank and liquid level stroke of gas-liquid energy converter was studies.The experimental results were analyzed to develop design guidelines.The guidelines are shown to be useful for obtaining the design parameters that would yield the desired hydrau- lic performance for the required operating conditions.
