Liquid jet

Fig. 3. Liquid jet produced during collapse of a cavitation bubble near a solid surface. The width of the bubble is about 1 mm.

Here is a specification sheet for steam jet and liquid jet ejectors. It contains data needed by the manufacturer to design and quote an ejector for a specific application. 

Location The postulated release would occur at an elevation of about 6 m above ground level (a.g.l.) and in a horizontal direction. The flashing liquid jet is likely to impact on surrounding equipment. 

The liquid jet from the DLI probe has to be initiated at atmospheric pressure, i.e. before insertion of the interface into the mass spectrometer, and, for best performance, the spray direction has to be coaxial to the probe. Any deviation from this, however slight, tends to produce changes in the mass spectrum obtained.

Developed by Freeman and Tavlarides [45,46], and based on the liquid jet technique [47,48], the LJRR provides a method of measuring liquid-liquid reaction kinetics with direct contact, known interfacial area, renewable interface, and reasonably defined hydrodynamics. This method operates by employing an aqueous liquid jet in a concurrent, coaxially flowing organic solution, shown schematically in Fig. 8.

For blending flammable liquids, the use of liquid jets should be considered as an intrinsically safer option see Fossett and Prosser (1949). 

In a biphasic solid-liquid medium irradiated by power ultrasound, major mechanical effects are the reduction of particles size leading to an increased surface area and the formation of liquid jets at solid surfaces by the asymmetrical inrush of the fluid into the collapsing voids. These liquid jets not only provide surface cleaning but also induce pitting and surface activation effects and increase the rate of phase mixing, mass transfer and catalyst activation. 

They also discussed the excitation mechanism of alkali-metal atoms as follows. The addition of a metal species from a liquid solution into cavitating bubbles is through the ablation of the bubble-liquid interface, the ablation of liquid jet or the evaporation of droplets, since the evaporation of salt is negligible. The salt molecules are released and decomposed into atoms via homolysis, analogous with the projection into a flame of metal species from salt solutions. The metal atoms are... 

Various hollow-cone simplex atomizers (Fig. 2.1) have been developed for combustion applications, differing from each other mainly in the way that swirl is imparted to the issuing liquid jet. In these atomizers, swirl chambers may have conical slots, helical slots (or vanes), or tangential slots (or drilled holes). Using thin, removable swirl plates to cut or stamp the swirl chamber entry ports leads to economies of the atomization systems if spray uniformity is not a primary concern. Large simplex atomizers have found applications in utility boilers and industrial furnaces. Oil flow rates can be as high as 67 kg/min.
