Application of Critical Energy Density Concept for Minimum Ignition Energy Determination

Journal of Electrostatics
This study presents a new concept, referred to as Critical Energy Density (CED), for estimating the Minimum Ignition Energy (MIE) of organic powders. Only readily experimental data, such as granulometric analysis, thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC), are required for running the mathematical model.

RANS Simulation of Minimum Ignition Energy of Stoichiometric and Leaner CH₄/Air Mixtures at Higher Pressures in Quiescent Conditions

Fire
Minimum ignition energy (MIE) has been extensively studied via experiments and simulations. However, our literature review reveals little quantitative consistency, with results varying from 0.324 to 1.349 mJ for ϕ = 1.0 and from 0.22 to 0.944 mJ for ϕ ...

Minimum Ignition Energy in a Hygrogen Combustible Mixture [PDF]

, 2011
In this thesis the Minimum Ignition Energy, in a hydrogen-air system, is studied by Direct Numerical Simulations (DNS) in a program called the Pencil Code. The heat source used to achieve ignition is modeled by a Gaussian temperature distribution.
