Theory of deflagration in disordered media

Physical Review E, 2017
The conventional theory of burning works well in the case of uniform media where all system parameters are spatially independent. We develop a theory of burning in disordered media. In this case, rare regions (hot spots) where the burning process is more effective than on average may control the heat propagation in an explosive sample.

Advanced Technologies for Characterizing and Detecting Battery Thermal Failure: A Review

Advanced Science, Volume 13, Issue 33, 15 June 2026.
Illustration of advanced characterization techniques to predict battery thermal failure. ABSTRACT Energy storage is essential in accelerating the global transition toward clean and sustainable energy across various sectors. Lithium‐ion batteries (LIBs) have become increasingly significant for energy storage due to their high energy density, low ...

Propagation Characteristics of Aluminum/Propylene Oxide Multiphase Cloud Explosion With Different AlH3 Ratios and Initiation Energies

Safety Science and Technology, Volume 1, Issue 2, June 2026.
Explosion process of propylene oxide (PO)/Al/AlH3/air was investigated. The PO/Al/AlH3/air multiphase clouds under strong ignition detonation have reached a quasi‐detonation state. ABSTRACT Fuel‐air explosives (FAE) are an important source of explosion energy. The density advantage of aluminum hydride (AlH3) dust is obvious compared with that of liquid

Graphene‐Skinned Alumina Fiber: Continuously Scalable Fabrication and Its Electrothermal Application in Fiber‐Reinforced Polymer Composites

Advanced Science, Volume 13, Issue 28, 18 May 2026.
Graphene‐skinned alumina fiber (GAF) is a new composite with graphene conformally grown on individual alumina fibers via chemical vapor deposition (CVD). GAF's dynamic, continuous and scalable production is achieved by using a home‐made roll‐to‐roll (RTR) CVD system featuring integrated degumming and growth chambers. GAF possesses tunable conductivity,

Numerical Simulations of Very Low Velocity Impacts and Ignition of an Explosive Confined by a Thin Case

Propellants, Explosives, Pyrotechnics, Volume 51, Issue 3, Page 446-455, March 2026.
A low‐speed impact (around one meter per second) of a metallic tip on an explosive confined by a thin plate is simulated. The heat due to friction between the tip and the plate and the one due to the deformation of the plate are not transfered to the ignited zone.

Experimental and ReaxFF‐MD Insights Into the Suppression Mechanism of Melamine Cyanurate on Aluminum Dust Explosion

Safety Science and Technology, Volume 1, Issue 1, March 2026.
This study experimentally determined that the critical suppression concentration of MCA for 30 μm aluminum dust is 750–800 g/m3. An atomic‐scale Al/suppressants combustion suppression model was established, revealing the microscopic mechanism that hinders oxidation and combustion of cAl atoms, and elucidating the synergistic physical–chemical ...

Effect of Particle Size Distribution on the Explosion Intensity of Hydrogen Direct‐Reduced Iron Dust

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
Steel production using direct‐reduced iron (DRI) in an electric arc furnace with natural gas has a lower carbon footprint compared to the blast furnace route (Bhaskar et al., 2019). When iron ore is reduced using hydrogen, the resulting product—H‐DRI—represents a key pathway to green steel and is increasingly used as a feedstock in industrial ...

Investigations of Deflagration in a Four-Litre-Autoclave under Atmospheric and Non-Atmospheric Conditions

Chemical Engineering Transactions, 2015
A four-litre-autoclave was used to perform deflagration tests in a closed vessel. The aim was to investigate the suitability of this autoclave and to evaluate different parameters influencing the deflagration.
