Impacts of Organic Structures and Inherent Minerals of Coal on Soot Formation during Pyrolysis
Energies, 2019 The pyrolysis of four pairs of raw and acid-washed coals under N2 atmosphere was carried out in a drop tube reactor at 1250 °C. The results show that both organic structures and metal elements have an important influence on the formation of soot ...

Forced Draught Impact on Externally Venting Flames: An Experimental and Numerical Investigation
Fire and Materials, EarlyView.ABSTRACT Wind can significantly influence fire development and spread in urban and forest environments causing fatal consequences for the public, the first responders, and the environment. Wind‐driven fires can have a significant impact on structural fires as wind can increase the fire's intensity, development, and flame spread.

Experimental and Numerical Investigation of Cedar Façade Flame Spread With Respect to Sidewall
Fire and Materials, EarlyView.ABSTRACT In response to growing energy conservation and carbon neutrality efforts, façade systems incorporating wooden materials have attracted increasing attention, which in turn raises concerns about their combustibility. This study presents a combined experimental and numerical investigation of flame spread along cedar façades.

Fire and Materials, EarlyView.ABSTRACT Fire sources in actual compartment fires exhibit a predominantly uneven spatial distribution. In this context, the impact of the height and location of the fire source, as well as the heat release rate (HRR) of the fire, on the thermal characteristics of Externally Venting Flames (EVF) is experimentally investigated.

Geological Journal, EarlyView.Chemical states of Se and Br atoms in the KPg boundary sediments from Stevns Klint were studied using XAFS spectroscopy. The high concentrations of Se4+ could become an index of the degree to which the global environment was soiled with dust and ash derived from impact ejecta or volcanic eruptions.
