One of the important choices for achieving decarbonization goals on a large scale is the
extensive use of H 2. However, the highly reactive nature of H 2 often leads to challenges …

Experimental study on the unconfined lean premixed NH 3/CH 4/air flames with three CH 4
fractions of 0, 50%, and 100% stabilized on a bluff-body and swirl burner was investigated …

An experimental study on the compact lean premixed flames stabilized on a bluff-body and
swirl burner is performed. The flames are featured with a strengthened Inner Recirculation …

Blow-off of swirl flames as well as its mechanism are fundamental issues and attract
continuous attention due to its wide application in modern combustors. This study …

The blow-off is one of the typical flame extinction mechanisms, and such a principle has
been widely used in firefighting when the water-based extinguisher is limited. This work …

Large eddy simulations of turbulent swirl-stabilised flames gradually approaching blow-off
conditions in a gas turbine model combustor are undertaken. The global equivalence ratio of …

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 …

In this paper, local flame and flow properties of propagating premixed turbulent propane/air
flames were derived by two-dimensional time-resolved Mie scattering and PIV methodology …

The traditional method using spark electrode ignition in annular combustors lacks safety due
to its long ignition delay and deficiencies in reliability and repeatability. The present work …

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 …
