Premixed flame ignition is a fundamental issue in combustion. A basic understanding of this
phenomenon is crucial for fire safety control and for the development of advanced …

Hydrogen has been conceived as an alternative to hydrocarbons to achieve a carbon–
neutral society, with ammonia emerging as the most practical hydrogen carrier for long …

In the context of explosion protection, very conservative safety factors need to be
considered, eg in the design of electrical devices. This is due to standards which are mainly …

Numerical simulations were carried out in order to study the channel expansion of a low-
energy spark in the air after the spark breakdown that resulted in the formation of initial arc …

Forced ignition is one of the most fundamental and important combustion problems. It is
used in advanced engines and closely related to fire safety and accidental explosion. In this …

In this work, the influence of different experimental parameters (electrode gap, electrode
shape, pressure and gas component) on spark discharge characteristics is investigated. The …

The paper presents a comparative study of a spark discharge evolution in nitrogen for cases
of its isothermal and adiabatic compressions. A numerical model of a spark channel …

The spark discharge of an aircraft plasma jet igniter is studied using high-fidelity numerical
simulations and X-ray radiography measurements. The target problem here features the …

The present study addresses effects of pressure wave disturbance on end-gas autoignition
behavior and subsequent pressure wave development, which are of particular interest for …

Ammonia is an attractive hydrogen carrier and potential fuel which could play a role in
decarbonizing process heat, power or transport applications. However, the combustion …
