WebJun 14, 2005 · 1 Introduction. The entrainment of air into a pool of water as a result of water jet impingement has been of interest in many facets of engineering. For a water jet which is continuously pouring into an otherwise calm free surface, the entrainment of air is in the form of bubbles being “dragged” below the free surface. 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 … WebSep 1, 2024 · Spray angle increases with the water jet velocity, air flow rate and impinging angle.
