Generation and Breakup of Worthington Jets After Cavity Collapse
Helped by the careful analysis of their experimental data, Worthington & Cole (1897, 1900) described roughly the mechanism underlying the formation of high-speed jets ejected after the impact of an axisymmetric solid on a liquid-air interface. They made the fundamental observation that the intensity of these sharp jets was intimately related to the formation of an axisymmetric air cavity in the...
متن کاملDesigning and Manufacturing the Multiple Jets Simulator and Experimental Investigation of the Multiple Jets in Crossflow
Designing and manufacturing the multiple jets simulator and experimental investigation of the multiple jets in crossflow at low velocity ratios have been studied Together with design and build a low-speed wind tunnel. A specific rake is used to determine the flow field pressure and changes in static pressure measured by pressure taps in the near field of the jets. There are generally three regi...
متن کاملDouble Layers and Plasma-wave Resistivity in Extragalactic Jets: Cavity Formation and Radio-wave Emission
For estimated values of the currents carried by extragalactic jets, current-driven electrostatic-waveand electromagnetic-wave-produced resistivities do not occur. Strong plasma double layers, however, may exist within self-maintained density cavities, the relativistic double-layer-emitted electron, and ion beams driving plasma-wave resistivities in the lowand high-potential plasma adjacent to t...
متن کاملBlue jets and gigantic jets
An overview of general phenomenology and proposed physical mechanisms of large scale electrical discharges termed ‘blue jets’ and ‘gigantic jets’ observed at high altitude in the Earth’s atmosphere above thunderstorms is presented. The primary emphasis is placed on summarizing available experimental data on the observed morphological features of upward jet discharges and on the discussion of re...
