Experimental investigation of a control synthetic jet

open access: yesEPJ Web of Conferences, 2012
Synthetic jets were used in previous studies to control a continuous round air jet. This study focuses on the single synthetic jet, which is measured using Constant Temperature Anemometry (CTA) and Particle Image Velocimetry (PIV).

Current-Driven Kink Instability in Magnetically Dominated Rotating Relativistic Jet

open access: yesEPJ Web of Conferences, 2013
We have investigated the influence of jet rotation and differential motion on the linear and nonlinear development of the current-driven (CD) kink instability of force-free helical magnetic equilibria via threedimensional relativistic magnetohydrodynamic

On the Origin and Nature of Double-Double Radio Galaxies

open access: yesGalaxies
Double-double radio galaxies (DDRGs) display inner and outer jets or lobes thought to result from intermittent accretion. Due to randomly triggered accretion events, the lifetime of the retriggered jet is not expected to have any connection to the time ...

Soft drop groomed jet angularities at the LHC

open access: yesPhysics Letters B, 2019
Jet angularities are a class of jet substructure observables where a continuous parameter is introduced in order to interpolate between different classic observables such as the jet mass and jet broadening.

Numerical Study on Pulsed Jet Coupling Effect and Projectile Pitching Motion

open access: yesSpace: Science & Technology
The pulsed jet with direct force control can provide a fast and environment-free control scheme. However, a complex jet interference occurs during the establishment and decay of the pulsed jet.

Swift J1727.8–1613 Has the Largest Resolved Continuous Jet Ever Seen in an X-Ray Binary

open access: yesThe Astrophysical Journal Letters
Multiwavelength polarimetry and radio observations of Swift J1727.8–1613 at the beginning of its recent 2023 outburst suggested the presence of a bright compact jet aligned in the north–south direction, which could not be confirmed without high-angular ...

Study on flow characteristics of a synthetic jet by using a vortex method

open access: yesNihon Kikai Gakkai ronbunshu, 2016
A synthetic jet is generated by an oscillating flow that a time-averaged mass flow is zero, unlike continuous jets. Synthetic jets have been used for various applications such as mixing enhancement and active controls. The present study investigated flow

Continuous Production of Carbon Nanostructures Using Plasma Jet

open access: yesJapanese Journal of Applied Physics, 2006
We have developed a continuous synthesis technique to produce carbon nanostructures using a well-controlled plasma jet. In this method, numerous fiber-like structures can be produced readily using CH4 gas and H2 gas without a catalyst. Without a catalyst, carbon nanostructures that have small diameters in the range of about 10–100 nm are mostly ...

CONTINUOUS CASTING OF EUTECTIC STRUCTURALSUPERFINE INGOTS OF SILUMINS WITHOUT APPLICATION OF IMPURITY MODIFIERS

open access: yesЛитьë и металлургия, 2010
It is shown that continuous horizontal casting with application of jet crystallizer and arrangement with flooded – jet repeated cooling enables to produce ingots of eutectic silumin with superfine microstructure without application of impurity modifiers.

Study on Pressure Fluctuation Characteristics of Hydraulic Pulsed Jet

open access: yesShiyou jixie, 2016
By producing instantaneous negative pressure and pulse shock at the bottomhole,the pulsed jet could reduce the pressure holding effect on the cuttings and improve the efficiency of rock breaking and cutting removing.On the basis of the established ...
