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

Combustion 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 ...

Influence of the Flow Rate of Oxidising Atmosphere on the Flame Spread Rate on the Surface of Organic Setlled Dust [PDF]

Research Papers Faculty of Materials Science and Technology Slovak University of Technology, 2013
Abstract The presented paper deals with determining the influence of the flow rate of oxidising atmosphere on the flame spread along the surface of the organic settled dust layer. We determined the rate of the flame spread on the surface of the organic settled dust layer (whole grain rye and spelt flour) with absolute moisture of 10 % wt., for the

Coagulative Granular Hydrogels with an Enzyme Catalyzed Fibrin Network for Endogenous Tissue Regeneration

Advanced Healthcare Materials, EarlyView.
Coagulative granular hydrogels are composed of packed thrombin‐functionalized microgels that catalyze the conversion of fibrinogen into a secondary fibrin network, filling the interstitial voids. This bio‐inspired approach stabilizes the biomaterial to match the robustness of bulk hydrogels without compromising injectability, mimicking the initial ...

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

Fire 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.

Mixed‐Metal Promotion in a Manganese‐Molybdenum Oxynitride as Catalyst to Integrate C─C and C─N Coupling Reactions for the Direct Synthesis of Acetonitrile from Syngas and Ammonia

Advanced Materials, EarlyView.
Transition metal oxy/carbo‐nitrides show great promise as catalysts for sustainable processes. A Mn‐Mo mixed‐metal oxynitride attains remarkable performance for the direct synthesis of acetonitrile, an important commodity chemical, via sequential C─N and C─C coupling from syngas (C1) and ammonia (N1) feedstocks.
