Swirling flows have been widely used to stabilize lean premixed combustion in various gas
turbines and furnaces. In such flows, understanding and characterizing the flame …

Abstract LOW SWIRL COMBUSTION is a novel method to stabilize lean premixed flames. In
order to utilize this stabilization method in gas turbines, it is required to gain a better …

The effect of inlet swirl on the flow development and combustion dynamics in a lean-
premixed swirl-stabilized combustor has been numerically investigated using a large-eddy …

The present work attempts to address unsteady flame dynamics in a lean-premixed swirl-
stabilized combustor, with attention focused on the effect of swirl on the flow development …

Optical and laser diagnostic measurements in a nonpremixed model gas turbine (GT) burner
have been performed to investigate the effect of an increase in thermal power on the flame …

Modern low-emission, lean premixed gas turbine combustion systems often rely on confined
swirling flows associated with sudden expansions to enhance flame anchoring. Through the …

In the swirl-stabilized flame studied, the heat release and the swirl were systematically
varied in order to quantify their effects on the internal recirculation zone, the mixing, the …

An open swirl-stabilized turbulent premixed flame is studied numerically. This study provides
a better understanding of the flame properties by simulating the flow field, combustion and …

Lean premixed combustion is one of the most promising technologies to reduce NOx
emission from gas-turbine combustors. However it is well known that lean premixed …

In most modern-day lean gas turbine combustors, flame is stabilized by swirl flows. A central
toroidal recirculation zone (CTRZ), developed by these swirl flows, helps to stabilize the …
