Flow characteristics of water jets in air
WebTypes Jet. A gas jet, fluid jet, or hydro jet is a nozzle intended to eject gas or fluid in a coherent stream into a surrounding medium. Gas jets are commonly found in gas stoves, ovens, or barbecues.Gas jets were commonly used for light before the development of electric light.Other types of fluid jets are found in carburetors, where smooth calibrated … WebCleaning water jets generally have the velocity range of ~80-200 m/s. They exhibit a high velocity coherent core surrounded by an annular cloud of water droplets moving in an entrained air stream. Leu et al. (1998) as well as Rajaratnam et al. (1994, 1998) have discussed the anatomy of high speed water jets in air; see Figure 1.

WebJet Flow. A plunging jet flow is defined as the impingement of a rapid flow (e.g. jet, supercritical flow) into a slower body of liquid (e.g. pool of liquid at rest, a tranquil … WebThey showed that with only an air mass flow of 1% of the liquid jets mass flow rate atomization is remarkably enhanced. The flow visualization results provided some description of the primary atomization region, such as burst of the bulging portions and the separation of the two liquid jets at impingement by the air jet at high air mass flow rates.
