A STUDY OF COMPARTMENT FIRE UNDER FORCED VENTILATION: EXPERIMENTAL AND COMPUTATIONAL FLUID DYNAMICS MODELING

International Islamic University Malaysia Engineering Journal, 2010
This paper discusses on the dynamic behavior of the flame and smoke inside a compartment fire. The compartment can be referred to a room, road tunnel, duct, compartment or a building.

Flame transfer function measurements of hydrogen-enriched reheat flames [PDF]

This study experimentally investigates the dynamic behavior of hydrogen-natural gas reheat flames, which are stabilized by both flame propagation and autoignition.

Prediction of combustion noise of an enclosed flame by simultaneous identification of noise source and flame dynamics [PDF]

, 2018
Large-Eddy Simulation (LES) is combined with advanced System Identification (SI) to simultaneously infer models for the source of combustion noise and the dynamic response to velocity fluctuations of a turbulent premixed flame.

Flame Suppression in Lithium‐Ion Batteries During Thermal Runaway Through Solvent Design Considering the Volatility–Flammability Relationship

Advanced Science, EarlyView.
An asymmetric sulfonate solvent forms thermally stable interphases and demonstrates non‐flammability, suppressing heat accumulation for safer, high‐performance lithium‐ion batteries. ABSTRACT An asymmetric sulfonate‐based linear solvent, 2,2,2‐trifluoromethyl mesylate (FMS), is designed and used as the primary solvent in liquid electrolytes to enhance ...

Intrinsic instability of flame-acoustic coupling

, 2014
This paper shows that a flame can be an intrinsically unstable acoustic element. The finding is clarified in the framework of an acoustic network model, where the flame is described by an acoustic scattering matrix.

From Fluoride Removal to Interfacial Reactivity Enhancement: Functionalized La3+‐Crosslinked B/CuO Energetic Microspheres

Advanced Science, EarlyView.
A fluoride adsorption‐functionalization strategy directly couples fluoride wastewater remediation with combustion performance enhancement of B/CuO energetic microspheres. Fluoride captured from wastewater is retained within the microspheres without adsorbent regeneration or disposal, simultaneously achieving pollutant removal and enhanced energetic ...

A numerical study of backdraft dynamics using a level-set nonadiabatic flamelet model

Journal of Thermal Science and Technology
The backdraft dynamics are numerically investigated using a proposed combustion model that attempts to accurately simulate the multi-combustion regime with a fast flame propagation in the inhomogeneous thermal condition.

Dynamics of unconfined spherical flames

, 2012
Using the soap bubble technique, we visualize the dynamics of unconfined hydrogen-air flames using high speed schlieren video. We show that for sufficiently weak mixtures, i.e., low flame speeds, buoyancy effects become important. Flame balls of a critical dimension begin to rise.

ZBTB18 Dysfunction Promotes Neuropathic Pain via CHD4‐based Epigenetic Disinhibition of CLIC1 Channels in Sensory Neurons

Advanced Science, EarlyView.
In this study, we identify a novel functional role of ZBTB18 in regulating trigeminal‐mediated neuropathic pain. Nerve injury reduces ZBTB18 in trigeminal ganglion neurons, impairing CHD4/NuRD recruitment and de‐repressing Clic1. Elevated CLIC1 enhances chloride channel activity and neuronal hyperexcitability, thereby driving pain.

Additive Manufacturing of High‐Performance Polymers for Extreme Environments

Advanced Science, EarlyView.
Additive manufacturing of high‐performance polymers for extreme environments is critically reviewed through an integrated chemistry‐processing‐structure‐property‐qualification framework. The review compares fused filament fabrication, selective laser sintering, and direct ink writing, linking rheology and thermal history to crystallization, defect ...
