    摘要: A method to improve a performance and efficiency of a liquid-gas eductor includes injecting a small amount of secondary gas into the primary motive liquid prior to the latter's arrival at the eductor. This measure simultaneously reduces the flow rate of motive fluid and maintains a level of secondary inducted flow such that the aggregate secondary flow is higher than without the intervention—for certain conditions. The additional work needed in introducing the injected secondary fluid, by auxiliary means, is a few percentage points of the work done by the motive fluid without the intervention. The quantity of secondary fluid inducted and injected by the eductor adopting the above measures approaches double than that of the secondary flow without the measure. The motive liquid volumetric flow rate is reduced slightly which with the enhanced aggregate secondary flow means that the energy efficiency of the eductor process is substantially increased.

    摘要: A Venturi device with a primary flow path and a secondary flow path introduced into the primary flow path, wherein a flow of one or more flowable mediums in the primary flow path and the secondary flow path creates a vortex generating a suction at an inlet of the Venturi device. A particulate burner system can be used to combust fuel emission byproducts by injecting fuel and air into a housing having a bottom plate with a round bottom opening for burners to inject fuel into a combustion chamber and a top plate with a round top opening for exhausting fuel emissions. A thruster system can be used to propel munition for deep earth penetration by using a thruster system having a transfer cone connected to a munition body.

    摘要: A pool aerator for pools with water recirculation circuit includes a hemispherical body and an atmospheric air intake pipe. The body of the aerator includes a rounded plastic object, having in the middle area a cylindrical portion, and at one end with a connecting means to the pool nozzle. The middle portion of the aerator body continues with a hemispherical dome. A Venturi tube made in the form of two intersected frustoconical spaces is positioned in the hemispherical dome. One of the intersected frustoconical spaces functions as an inlet and the other for mixing and discharging water mixed with air. The two axes of the intersected frustoconical spaces form an angle (α) between 10 and 20 degrees. The mixing hole communicates with a vertical cylindrical hole, in which the intake pipe is inserted by sliding, until the inner wall of the frustoconical hole is reached.
