Laboratory measurements in a turbulent, swirling flow [PDF]

Measurements of soot inside a flame-tube burner using a special water-flushed probe are discussed. The soot is measured at a series of points at each burner, and upon occasion gaseous constitutents NO, CO, hydrocarbons, etc., were also measured.

Heterogeneous reactions of particulate matter-bound PAHs and NPAHs with NO3/N2O5, OH radicals, and O3 under simulated long-range atmospheric transport conditions: reactivity and mutagenicity. [PDF]

, 2014
The heterogeneous reactions of ambient particulate matter (PM)-bound polycyclic aromatic hydrocarbons (PAHs) and nitro-PAHs (NPAHs) with NO3/N2O5, OH radicals, and O3 were studied in a laboratory photochemical chamber. Ambient PM2.5 and PM10 samples were

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.

The role of thermophoretic effect in the formation of soot from liquid fuels [PDF]

, 2016
In order to rationalize soot formation in two-phase combustion, the related dynamics can be conveniently studied in simpler systems. In the latest twenty years, experimental activity in drop towers and in the outer space have allowed to investigate the ...

Soot measurement in diluted methane diffusion flames by multi-pass extinction and laser-induced incandescence [PDF]

, 2018
Multi-pass cavity line-of-sight extinction (MPC-LOSE) and laser- induced incandescence (LII) techniques are deployed to measure the soot volume fraction in a series of nitrogen-diluted flames, which produce only ppm volume mass fractions of soot.

An Experimental Investigation on the Impact of Burner Height and Location on the Characteristics of Externally Venting Flames

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.

Retrieval of ice-nucleating particle concentrations from lidar observations and comparison with UAV in situ measurements [PDF]

, 2019
Aerosols that are efficient ice-nucleating particles (INPs) are crucial for the formation of cloud ice via heterogeneous nucleation in the atmosphere. The distribution of INPs on a large spatial scale and as a function of height determines their impact ...
