Centrally staged swirl combustion can effectively reduce NO x emission. However, the
complex combustion field is susceptible to producing large-scale coherent structures, such …

In a centrally-staged combustor, the stratified swirling flame often manifests a helical mode,
which is characterized by the emergence of helical vortices, including the precessing vortex …

The characteristics of spray/ambient gas flow and the turbulent mixing process significantly
influence the subsequent combustion feature. There are some related studies on the …

The present paper compares the flow structure and flame dynamics during combustion of
methane and syngas in a model gas-turbine swirl burner. The burner is based on a design …

This paper reports two distinct vortex-flame interaction mechanisms existing in a self-excited
V-shaped premixed flame. Time-resolved simultaneous measurements of particle image …

To investigate thermoacoustic instability and emission characteristics in premixed swirl
combustor, several low-emission swirlers with different vane stagger angles were designed …

The relationship between the flow field and flame propagation is essential in determining the
dynamics and effects of turbulent flow in an optical SI engine. In this study, high turbulence …

This work designs an axial/tangential swirl jet burner to establish stable CH 4/O 2/CO 2
combustion under a wide range of operating conditions. As the flow rate of the axial fuel …

The flame kernel propagation characteristics stemmed from the spark ignition of low-Re, non-
premixed propane (C 3 H 8) under varying air co-flow conditions were studied using DFCD …

The velocity distribution of flame is an important combustion dynamic parameter that is used
to analyze the stability, heat transfer and propagation of combustion. Digital particle image …
