Numerical investigation of forced ignition in laminar counterflow non-premixed methane-air flames
Simulations of forced ignition of non-premixed laminar counterflow flames are used to study the effect of strain rate on ignition success. A one dimensional calculation is performed, using detailed methane chemical kinetics and treating the spark as an ...

Combustion of turbulent lean mixtures by plasma jet ignition.
In order to confirm quantitatively the performance and characteristics of the plasma jet ignition in turbulent lean mixtures, combustion tests were carried out with varying the governing parameters of the plasma jet ignition. three plasma cavity sizes of 37, 75, and 170 mm3, three orifice diameters of 1, 2, 5 and 4 mm, and three discharge energies of 0.

Large eddy simulation of ignition and combustion of ethylene/air turbulent jet diffusion flame with reduced kinetic mechanism [PDF]
In this paper, unsteady process of ignition and combustion of turbulent plane-jet diffusion flame of ethylene/air at varied fuel/air ratios is numerically simulated with Large Eddy Simulation (LES) and a reduced kinetic mechanism of ethylene. The kinetic

A Review of Failure Modes and Safety Strategies of Lithium‐Ion Batteries from Materials to Systems
A cascade‐aware framework is presented for lithium‐ion battery safety, linking thermal runaway initiation, acceleration, runaway reaction, and propagation with material‐, cell/pack‐, and system‐level interventions. By integrating failure mechanisms, quantitative safety indicators, and staged interception strategies, this review highlights how safer ...
