Effect of Stretch on Local Burning Velocity of Premixed Turbulent Flames

Journal of Thermal Science and Technology, 2007
The effect of positive stretch on the local flame properties of turbulent propagating flames in the flamelet regime was investigated experimentally for methane-, hydrogen- and propane-air mixtures with lean and rich having nearly the same laminar burning

STUDY OF THE EFFECT OF ELEVATED PRESSURES ON THE LAMINAR BURNING VELOCITY OF PROPANE-AIR MIXTURES

Diyala Journal of Engineering Sciences, 2015
Laminar burning velocities were obtained for three specific equivalence ratios of propane –air mixtures (Ø= 0.8, 1.0 & 1.3). The effect of elevated pressures at variable initial temperatures was also analyzed.

Aerogel Fiber: A One‐Dimensional Programmable Porous Matter for Next Thermal Management Materials

Interdisciplinary Materials, EarlyView.
Aerogel fibers are redefined as one‐dimensional programmable porous matter, where thermal transport is governed by multiscale pathway engineering. By reconstructing and decoupling transport pathways from molecular to textile scales, these systems integrate insulation, radiative cooling, and adaptive thermal regulation.
