The present article investigates the interactions between the pilot and main flames in a novel
stratified swirl burner using both experimental and numerical methods. Experiments are …

This paper studies the flame dynamics near lean blowout (LBO) conditions in a stratified
swirl burner. The novel BASIS burner is used and fueled with premixed methane/air mixture …

The simulation of turbulent stratified swirling flame has received much attention recently
owing to its importance for research on power generation and transportation devices. In this …

Effects of swirl divergence cup and the central bluff body on premixed flame response with
