Heat transfer from swirling impinging jets [PDF]

open access: yes, 1980
This thesis is concerned with the determination of the local and average mass/heat transfer--from swirling jets impinging orthogonally onto flat surfaces.

Comparison of flow and dispersion properties of free and wall turbulent jets for source dynamics characterisation [PDF]

open access: yes, 2009
The objective of this paper is to provide an investigation, using large eddy simulations, into the dispersion of aircraft jets in co-flowing take-off conditions.

A Measurement of W+jets Z+jets with the ATLAS Detector [PDF]

open access: yes, 2015
PhDA study is presented on the production of vector boson (W and Z0) events in association with recoiling hadronic activity in the form of hadronic jets, using proton-proton collisions at the LHC.

Unconventional Mechanisms of Heavy Quark Fragmentation

open access: yesUniverse, 2023
Heavy and light quarks produced in high-pT partonic collisions radiate differently. Heavy quarks regenerate their color field, stripped-off in the hard reaction, much faster than the light ones and radiate a significantly smaller fraction of the initial ...

The Origin of Matter at the Base of Relativistic Jets in Active Galactic Nuclei

open access: yesUniverse, 2020
The generation of relativistic jets in active sources such as blazars is a complex problem with many aspects, most of them still not fully understood.

Intermediate-Mass Black Holes: The Essential Population to Explore the Unified Model for Accretion and Ejection Processes

open access: yesGalaxies, 2023
We study radio and X-ray emissions from intermediate-mass black holes (IMBHs) and explore the unified model for accretion and ejection processes. The radio band survey of IMBH (candidate) hosted galaxies indicates that only a small fraction (∼0.6%) of ...

Leadership succession patterns in the apostolic church as a template for critique of contemporary charismatic leadership succession patterns

open access: yesHTS Teologiese Studies/Theological Studies, 2016
The pattern of leadership succession observed globally in most contemporary Pentecostal movements and churches can be characterised as dynastic succession. Yet historic modern Pentecostalism (in the Azusa tradition) prided itself on being biblical.

Binary Central Stars of Planetary Nebulae

open access: yesGalaxies, 2020
It is now clear that a vast majority of intermediate-mass stars have stellar and/or sub-stellar companions, therefore it is no longer appropriate to consider planetary nebulae as a single-star phenomenon, although some single, isolated stars may well ...

Binary Interactions, High-Speed Outflows and Dusty Disks during the AGB-To-PN Transition

open access: yesGalaxies, 2018
It is widely believed that the dramatic transformation of the spherical outflows of AGB stars into the extreme aspherical geometries seen during the planetary nebula (PN) phase is linked to binarity and driven by the associated production of fast jets ...

Active aerodynamics control of simplified vehicle body in a crosswind condition

open access: yesThe Journal of Engineering, 2020
In this study, the authors used a steady jet from a slit nozzle to control the bi-stable aerodynamics of a simple vehicle model under crosswind conditions.
