Variable air blast fireball of HMX/Al with tailored gradient structures
Case Studies in Thermal EngineeringAir 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 ...

Hydrogen Fireball Consequence Analysis [PDF]
Chemical Engineering Transactions, 2020 A fireball may occur after the catastrophic rupture of a tank containing a flammable substance such as a fuel, if an ignition source is present. The fireball is identified by the combustion of the flammable cloud created after the fuel release and ...

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

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

Geophysical 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.

Mathematics, 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 ...
