Critical Criterion for Flame Spread Acceleration of Concave Surfaces with Different Curvatures
FireConcave surface is a common geometry in both industrial buildings and natural environments; the flame spread behaviors on this special surface are worth studying, while few studies have been completed yet.

Journal of Combustion, 2011 Two solid pyrolysis models are employed in a concurrent-flow flame spread model to compare the flame structure and spreading characteristics. The first is a zeroth-order surface pyrolysis, and the second is a first-order in-depth pyrolysis.

Journal of Combustion, 2022 Fire occurring in the chaparral behaves as a crown fire, a dual-layer fire that typically ignites in a dead surface fuel layer and transitions to an elevated live crown layer where it continues to spread.

Laser‐Induced Graphene from Waste Almond Shells
Advanced Functional Materials, EarlyView.Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Effects of boundary layer displacement and separation on opposed-flow flame spread [PDF]
, 1997 An analysis is presented of the viscous-inviscid Interaction region around the tip of a flame spreading over the surface of a solid fuel in a forced laminar high reynolds number air stream that opposes the flame propagation. Through the interaction, the

Flame spread of droplet-cloud elements with two-droplet interaction in microgravity
Journal of Thermal Science and Technology, 2017 This research conducted microgravity experiments to investigate the flame-spread characteristics of the fuel-droplet-cloud element with uneven droplet spacing, which is a basic element of a randomly distributed droplet cloud at the critical condition for

Fire behaviors along timber linings affixed to tunnel walls in mines.
PLoS ONE, 2021 Timber linings are applied as primary supports in the tunnel fault and fracture zones of mines. These linings are essential to prevent broken rock from falling during the occurrence of exogenous fires. In this study, experiments and numerical simulations
