Modelling of opposed flame spread over thin electric wires: estimation of flame spread rates and limiting oxygen concentrations

open access: yesCombustion Theory and Modelling
A model of opposed flame spread along thin electric wires is developed to estimate the variation of flame spread rate (Vf) with oxygen concentrations and oxidiser flow velocity. The length of pyrolysis zone (Lpy) and Vf are treated as eigenvalues of the problem, and one-dimensional energy balance equations for the wire core and insulation are ...

The influence of small mass loss rate peaks on the rate of spread of predictive flame spread simulations: A theoretical study

open access: yesFire Safety Journal
Peaks in the mass loss rate (MLR) curve derived from thermogravimetric analysis (TGA) are commonly used to infer the pyrolysis rates of solid fuels. While the main peaks are often modelled, smaller MLR fluctuations are typically neglected, leading to discrepancies between models and experiments.

Architecture‐Driven Functional Coupling in Vertically Aligned Nanocomposites

open access: yesAdvanced Functional Materials, EarlyView.
Vertically aligned nanocomposites define a growth‐engineered architecture in which vertical interfaces, strain fields, defect pathways, and phase connectivity are created simultaneously. This review shows how these architectural features couple ferroic, optical, ionic, electrochemical, and device responses, establishing design rules and open challenges

Parametric study of the thermodynamic algorithm for the prediction of steady flame spread rate [PDF]

open access: yesComputer Research and Modeling, 2013
The stationary flame spread rate has been calculated using the relationship based on the thermodynamic variational principle. It has been shown that proposed numerical algorithm provides the stable convergence under any initial approximation, which could be noticeably far from the searched solution.

Unified Pressure and Field Response Across Distinct Charge‐Order Regimes in Ti‐Doped CsV3Sb5

open access: yesAdvanced Functional Materials, EarlyView.
We microscopically investigate the interplay between charge order and superconductivity in a kagome superconductor across regimes of long‐ and short‐range charge order. Hydrostatic‐pressure and magnetic‐field μSR$\mu{\rm SR}$ measurements reveal remarkably similar superconducting and normal‐state time‐reversal‐symmetry‐breaking responses in both ...
