Properties of jets and wakes [PDF]

open access: green, 1959
This thesis is a study of the affect of differences in the density of a fluid on the mixing regions of jets, which may be laminar or turbulent. These differences in density are present for three main reasons, namely; when the speed of the fluid is of the same order of magnitude as the local speed of sound; when there are large temperature differences ...

Visualizing How Jet Structure Shapes Jet Wakes [PDF]

open access: yesEPJ Web of Conferences
The ATLAS Collaboration has developed a method to analyze largeradius jets composed of skinny R = 0.2 subjets in heavy-ion collisions. We first demonstrate that the measurements pioneered by ATLAS constrain the value of Lres, the resolution length of QGP—

Acoustic modes in jet and wake stability [PDF]

open access: greenJournal of Fluid Mechanics, 2019
Motivated by recent studies that have revealed the existence of trapped acoustic waves in subsonic jets (Towneet al.,J. Fluid Mech., vol. 825, 2017, pp. 1113–1152), we undertake a more general exploration of the physics associated with acoustic modes in jets and wakes, using a double vortex-sheet model.

The wake of the wedge in the plane jet.

open access: bronzeTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1985
本研究はエッジ音を積極的に利用し,物体からのはく離渦を制御することを目的とする。その一環として,エッジ音の発生を伴う物体後流の特性を調べた。その結果,噴流中に置かれた物体後流と一様流中のそれとは速度欠損部の広がりに違いがみられ,また,後流域の特性,エッジ音と物体からの渦放出周波数とが密接に関係していることなどを明らかにした。

Imaging the wakes of jets with energy-energy-energy correlators

open access: yesJournal of High Energy Physics
As the partons in a high energy jet propagate through the droplet of quark-gluon plasma (QGP) produced in a heavy-ion collision they lose energy to, kick, and are kicked by the medium.

Jet wake from linearized hydrodynamics [PDF]

open access: yesJournal of High Energy Physics, 2021
AbstractWe explore how to improve the hybrid model description of the particles originating from the wake that a jet produced in a heavy ion collision leaves in the droplet of quark-gluon plasma (QGP) through which it propagates, using linearized hydrodynamics on a background Bjorken flow.

Analysis of Upstream Turbulence Impact on Wall Heat Transfer in an Acoustic Liner with Large-Eddy Simulations

open access: yesApplied Sciences, 2023
Acoustic liners of aircraft fan ducts generate synthetic jets that interact with the boundary layer of the incident grazing flow. Such an interaction leads to complex wall heat transfer, which has been scarcely studied.

LiSBOA (LiDAR Statistical Barnes Objective Analysis) for optimal design of lidar scans and retrieval of wind statistics – Part 2: Applications to lidar measurements of wind turbine wakes [PDF]

open access: yesAtmospheric Measurement Techniques, 2021
The LiDAR Statistical Barnes Objective Analysis (LiSBOA), presented in Letizia et al. (2021), is a procedure for the optimal design of lidar scans and calculations over a Cartesian grid of the statistical moments of the velocity field.

Simulation of building-induced airflow disturbances in complex terrain using meteorological-CFD coupled model

open access: yesMeteorologische Zeitschrift, 2022
Tiny anticyclonic vortices have been observed at the arrival runway corridor to the east of the central runway of the Hong Kong International Airport many times. However, it is not sure about the cause of such vortices.

Disentangling jet modification in jet simulations and in Z+jet data

open access: yesJournal of High Energy Physics, 2022
The selection of jets in heavy-ion collisions based on their p T after jet quenching is known to bias towards jets that lost little energy in the quark-gluon plasma.
