The flame expansion process (“light-round”) during the ignition transient in annular
combustors depends on a number of parameters such as equivalence ratio (and hence …

Abstract Large Eddy Simulations (LES) are carried out targeting an unconfined premixed
bluff body burner operated with ethanol, n-heptane, Jet A, and a Sustainable Aviation Fuel …

The flame behaviour and the lean blow-off (LBO) mechanism of a multi-burner linear
arrangement of five identical burners each fitted with a central bluff body and a swirler up …

The ignition of kerosene spray in an aero-engine combustor is complex due to the fuel
injection, mixing, and swirl flow. To explore the influence of ignition position on the ignition …

This work presents a series of simulations of the light-round process in a premixed annular
combustor, consisting of 18 individual swirl bluff body burners, using improvements to the …

Aiming to improve the stabilization of unstable swirling turbulent premixed flames, an
actively controlled swirler and electrical hardware and control software are developed …

Ignition and lean blowout characteristics are an important performance index of the
Aeroengine combustor, which is directly related to the reliability of the whole engine. The …

A previously-developed low-order Lagrangian stochastic model for ignition of premixed and
non-premixed flames is modified in this paper to improve the numerical prediction of the light …

The minimum ignition equivalence ratio of the strut stabilizer is an important parameter in the
design of integrated afterburners. The ignition location significantly affects the ignition …

The SPINTHIR model, which is a Lagrangian stochastic low-order model for ignition
validated and applied to several premixed and non-premixed cases, is modified in this …
