Global and Detailed Calculation of Tube Wall Temperature in a Process Furnace Steam Superheater

open access: yesChemie Ingenieur Technik, EarlyView.
This study presents a comparison between an iterative global model and multiple approaches to a new non‐iterative model with the purpose of predicting tube wall temperature of a superheater. The results show that the non‐iterative method achieves sufficient accuracy while improving the prediction of local temperature distribution and better ...

Formation of PAHs and Carbonaceous Solids in Gas-Phase Condensation Experiments [PDF]

open access: yes, 2009
Carbonaceous grains represent a major component of cosmic dust. In order to understand their formation pathways, they have been prepared in the laboratory by gas-phase condensation reactions such as laser pyrolysis and laser ablation.

Protocol for Reconstituting Adaptor‐Mediated Activation of Full‐Length Kinesin‐1

open access: yesCytoskeleton, EarlyView.
ABSTRACT Kinesin‐1 is a member of the kinesin superfamily that plays an essential role in intracellular cargo transport. In the absence of cargo, Kinesin‐1 exhibits low motor activity due to autoinhibition. Multiple studies have demonstrated that adaptor proteins, which link cargos to Kinesin‐1, can activate Kinesin‐1 by releasing the autoinhibition ...

Numerical Simultaneous Determination of Non-Uniform Soot Temperature and Volume Fraction from Visible Flame Images

open access: yesEnergies, 2022
This paper presents a method to invert the two-dimensional distribution of a temperature and volume concentration of soot particles from color images. By using numerical simulation, the temperature field and particle volume-concentration field of a non ...

Absolute soot volume fraction measurement by laser induced incandescence calibration in sooting turbulent diffusion flame

open access: yes, 2023
This paper mainly describes the laser based method we developed for quantitative measurements of soot volume fraction applied in two turbulent flames of diesel and E85 (gasoline/ethanol mixture) stabilized on a home-made jet burner working with liquid fuels.

Forced Draught Impact on Externally Venting Flames: An Experimental and Numerical Investigation

open access: yesFire 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.
