Influence of Particle Size, Moisture, and Cloud Density on Wood Dust Ignition

open access: yesChemie Ingenieur Technik, EarlyView.
The ignition and combustion of particle clouds are strongly affected by particle interactions. This study uses spectroscopy to examine effects of particle size, water content, and cloud density. Results show ignition delay rises with larger size and density, whereas combustion duration depends mainly on water and density due to moisture‐driven ...

Ignition delay time correlations for distillate fuels

open access: yes, 2017
Ignition delay times were measured behind reflected shock waves in a shock tube for a wide variety of distillate fuels over a range of temperatures, pressures and mixtures. The fuels studied include: jet fuels (JP-5, JP-8, and Jet A), rocket propellants (

Design and implementation of a 3D‐printed modular distillation tower for experimental teaching in chemical engineering

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Several authors have reported the disconnection between the skills, abilities, and attitudes of graduates from STEM careers with the current needs of the labour market. In science and engineering fields, research has found the need for interdisciplinary approaches that encourage meaningful learning.

Spontaneous Ignition Delay of Fuel Sprays

open access: yesTransactions of the Japan Society of Mechanical Engineers, 1960
Spontaneous ignition delay of fuel sprays injected into hot air in the temperature range from 250° to 900°C was measured at atmospheric pressure for various type of fuels. It is found that Arrhenius plot of the ignition delay is not linear but is bent at a temperature region from 600° to 700°C, and that the fluctuation in time lag becomes wider as the ...

A‐optimal model‐based design of experiments for processes with uncertain inputs

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
Abstract Model‐based design of experiments (MBDoE) techniques are tools for selecting experimental conditions that enable accurate parameter estimation for mechanistic models. Most MBDoE approaches assume that the selected experimental conditions will be implemented perfectly, without uncertainties in the independent variables.

Effect of background ionization on plasma ignition dynamics

open access: yes, 2017
The influence of background ionization on the ignition dynamics of the pulsed plasma plume is studied. The ignition delay time of each pulse is investigated by recording the voltage signal and the light emission signal.

Ultrafast Transitions in X‐Ray Irradiated Solids

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT In this review, we present current developments on modeling ultrafast transitions in solids triggered by intense, atto‐ to femtosecond pulses from X‐ray free electron lasers. This specific irradiation regime requires dedicated simulation tools based on theoretical and computational methods, involving the elements of classical and quantum ...

Single-pulse chemical shock tube for ignition delay measurements [PDF]

open access: yes, 2008
We describe a single-pulse chemical shock tube CST2 established for measuring the reaction rate of chemical reactions and ignition delay for fuels at high temperature along with the procedure for its calibration.
