The numerical investigation on the rolling decoupling of a canard-controlled missile using the jet control system

open access: yesEngineering Applications of Computational Fluid Mechanics, 2020
When the canard-controlled missile is conducting roll control, the asymmetric downwash induced by the canard impacts on the fins and produces a reverse rolling moment, resulting in the aerodynamic coupling between the canards and the fins.

Event Activity Measurements and Mid-Rapidity Correlations in 200 GeV pAu Collisions at STAR

open access: yesProceedings, 2019
These proceedings report preliminary measurements of correlations between mid-rapidity charged tracks and high-rapidity event activity (EA) at STAR for s NN = 200 G e V p+Au collisions taken in 2015.

Super-Resolved Image of M87 Observed with East Asian VLBI Network

open access: yesGalaxies, 2023
Obtaining high-resolution images at centimeter-or-longer wavelengths is vital for understanding the physics of jets. We reconstructed images from the M87 22 GHz data observed with the East Asian VLBI Network (EAVN) by using the regularized maximum ...

Unconditional jetting [PDF]

open access: yesPhysical Review E, 2008
Capillary jetting of a fluid dispersed into another immiscible phase is usually limited by a critical Capillary number, a function of the Reynolds number and the fluid properties ratios. Critical conditions are set when the minimum spreading velocity of small perturbations $v^*_-$ along the jet (marginal stability velocity) is zero.

The Jet Shape at NLL$'$ [PDF]

open access: yes, 2019
The jet shape is the fraction of the jet energy within a cone $r$ centered on the jet axis. We calculate the jet shape distribution at next-to-leading logarithmic accuracy plus next-to-leading order (NLL$'$), accounting for logarithms of both the jet ...

Passive scalar mixing downstream of a synthetic jet in crossflow [PDF]

open access: yes, 2008
An experimental investigation on passive scalar mixing due to the interaction of a synthetic jet with a thermal boundary layer is presented. From velocity measurements, performed by particle image velocimetry, two jet behaviours were identified.

DNS of turbulent Schmidt number and eddy diffusivity for reactive concentrations

open access: yesNihon Kikai Gakkai ronbunshu, 2014
The gradient diffusion hypothesis for turbulent mass fluxes of reactive scalar is investigated by using direct numerical simulations (DNS) of a planar jet with a second-order chemical reaction A+B→R.

Medium Recoils and background subtraction in JEWEL

open access: yes, 2016
\textsc{Jewel} is a fully dynamical event generator for jet evolution in a dense QCD medium, which has been validated for multiple jet and jet-like observables.

Equipartition Jet Model for the Seyfert 1 Galaxy 3C120 [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2003
The motion of 3C120 Jet relative to the core is reasonably uniform and the VLBI scale jet connects outwards to a VLA ˜ 100 kpc scale. We measured the jet width variation from the center and found some indication of a power law which indicates the jet ...

The polarisation of afterglow emission reveals GRB jet structure

open access: yes, 2004
We numerically compute light and polarisation curves of gamma-ray burst afterglows for various configurations of the jet luminosity structure and for different dynamical evolutions. We especially consider the standard homogeneous ``top hat'' jet and the `
