Recent discoveries and developments on the dynamic process of premixed turbulent spark
ignition are reviewed. The focus here is on the variation of turbulent minimum ignition …

Renewed interest in the use of high-speed ramjets and scramjets and more efficient lean
burning engines has led to many subsequent developments in the field of laser ignition for …

Centrally staged lean premixed pre-evaporation combustion technology has been used in
aero engines for its capability in effectively reducing NOx emissions while still providing …

Combustion is one of the most dominant energy conversion processes used in all areas of
human life, but global concerns over exhaust gas pollution and greenhouse gas emission …

This paper measures turbulent spark ignition probability and minimum ignition energy (MIE)
of the pre-vaporized iso-octane/air mixture at an equivalence ratio ϕ= 0.8 at 373 K with Le≈ …

A detailed study of ignition mechanisms in aeronautical burners is presented. Even in global
lean conditions, liquid fuel injection leads to a strong stratification of the mixture and the …

Previous work on spray flames has shown that different propagation mechanisms may occur
depending on the size and number density of droplets. In this work, the structure and …

Compared to quiescent premixed reactants, forced ignition of flowing/turbulent premixed
reactants is expected to be more difficult because of increased dissipation of the deposited …

Partly due to stringent restrictions on pollutant emissions, aeronautical engine
manufacturers target lean operating conditions which raise new difficulties such as …

The present work focuses on the early stages of flame-kernel development in laser-induced
spark ignited mixtures issuing out of a Bunsen burner. The time-scale of 3 µs to 1 ms …
