Experimental Investigation of Burning Liquids in Reduced Oxygen

Fire and Materials, Volume 50, Issue 4, Page 448-459, June 2026.
ABSTRACT The effects of oxygen concentration on combustion of gases have been investigated on fundamental levels in several studies. However, the same type of fundamental studies has not been made for liquid or solid fuels due to complex relationships between flame structure and changing mass loss rates (MLR).

Role of Nitridation Temperature in Multifunctional Properties of Sintered Reaction‐Bonded Silicon Nitride Ceramics

International Journal of Applied Ceramic Technology, Volume 23, Issue 3, June 2026.
ABSTRACT This study investigates the influence of nitridation temperature and sintering time on the microstructure and properties of sintered reaction‐bonded silicon nitride (SRBSN) ceramics. High‐purity silicon powder was used as the starting material, with Y2O3 and MgO as sintering additives.

Sessile water droplets on insulating surfaces subject to high AC stress effect of contact angle

, 2002
Surface pollution of outdoor high-voltage insulators is an important cause of flashover. We have undertaken an experimental study of electrical breakdown at the edges of a sessile water droplet on a planar, polymeric, insulating surface when subject to ...

Arc mapping

, 2010
Establishing a compartment fire's area of origin when it has been burning at post-flashover conditions is a difficult process. Burn patterns traditionally used by fire investigators following post-flashover fires can be erroneous.

Melt Grafting of Geometry‐Tailored Voltage Stabilizers for High‐Performance Polypropylene Insulation

Advanced Functional Materials, Volume 36, Issue 30, 13 April 2026.
A scalable one‐step melt grafting strategy is developed to enhance the dielectric properties of isotactic polypropylene by covalently incorporating thermally stable aromatic voltage stabilizers. This solvent‐free approach improves volume resistivity and DC breakdown strength through deep trap formation and charge localization, offering a sustainable ...

Computational investigation of flahover mechanisms using fire dynamics simulator (fds)

, 2011
A pilot study of the development of flashover in enclosure fires was performed using the Fire Dynamics Simulator (FDS) platform. Practical criteria for flashover commonly proposed in the literature were investigated in the context of FDS modeling to ...
