High-Speed Infrared Radiation Thermometer for the Investigation of Early Stage Explosive Development and Fireball Expansion [PDF]

open access: yesSensors, 2022
The understanding of blast loads is critical for the development of infrastructure that protects against explosions. However, the lack of high-quality experimental work on the characterisation of such loads prevents a better understanding of many ...

New, Spherical Solutions of Non-Relativistic, Dissipative Hydrodynamics [PDF]

open access: yesEntropy, 2022
We present a new family of exact solutions of dissipative fireball hydrodynamics for arbitrary bulk and shear viscosities. The main property of these solutions is a spherically symmetric, Hubble flow field. The motivation of this paper is mostly academic:

Multi-instrumental detection of a fireball during Leonids of 2019

open access: yesFrontiers in Astronomy and Space Sciences, 2023
During the 2019 Leonid meteor shower, the European Fireball Network recorded a bright fireball (meteor code: EN171119_041459) at 04:15:0.2 (UT) on 17 November 2019.

Variable air blast fireball of HMX/Al with tailored gradient structures

open access: yesCase Studies in Thermal Engineering
Air blast fireball of the composite explosive is an important way to destroy the target and effectively determines the damage effect. Herein, based on the effect of aluminum powder content on the explosion reaction kinetics of HMX-based aluminized ...

Multi-instrument observations of the Pajala fireball: Origin, characteristics, and atmospheric implications

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Meteor observations provide information about Solar System constituents and their influx onto Earth, their interaction processes in the atmosphere, as well as the neutral dynamics of the upper atmosphere.

Why a Hydrogen fireball should not be modelled as a BLEVE event

open access: yesChemical Engineering Transactions, 2022
The rapid increasing interest in the usage of Hydrogen has obviously triggered a lot of safety related questions. Apart from non-trivial questions about failure frequencies and ignition probabilities, the consequence modelling of potential events also ...

Exclusive Seismoacoustic Detection and Characterization of an Unseen and Unheard Fireball Over the North Atlantic

open access: yesGeophysical Research Letters, 2023
Small meteoroids that enter Earth's atmosphere often go unnoticed because their detection and characterization rely on human observations, introducing observational biases in space and time.

Prevention of Hazards Induced by a Radiation Fireball through Computational Geometry and Parametric Design

open access: yesMathematics, 2022
Radiation fireballs are singular phenomena which involve severe thermal radiation and, consequently, they need to be duly assessed and prevented. Although the radiative heat transfer produced by a sphere is relatively well known, the shadowing measures ...

On the Relative Usefulness of Fireballs [PDF]

open access: yes2015 30th Annual ACM/IEEE Symposium on Logic in Computer Science, 2015
In CSL-LICS 2014, Accattoli and Dal Lago showed that there is an implementation of the ordinary (i.e. strong, pure, call-by-name) $λ$-calculus into models like RAM machines which is polynomial in the number of $β$-steps, answering a long-standing question.
