Combustion characteristics of hydrogen in a test swirl combustor for a micro gas turbine.

CFD Insight of the Flow Dynamics and Velocity Fields in a Gas Turbine Combustor with a Swirl Flame

The computational fluid dynamics (CFD) simulations of gas turbine combustor were performed for CH4<span st...

Combustion characteristics of hydrogen–air premixed gas in a sub-millimeter scale catalytic combustor

A sub-millimeter scale catalytic combustor was fabricated. Platinum catalyst coated on a porous ceramics support was placed in the combustion chamber. The chamber, sized 10 10 1:5 mm was covered with a GaAs window which is transparent to infrared radiation. The conversion rate was measured using gas chromatography. The temperature distribution in the combustion chamber was measured with an infr...

Effect of swirl on combustion dynamics in a lean-premixed swirl-stabilized combustor

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-simulation (LES) technique along with a level-set flamelet library approach. Results indicate that when the inlet swirl number exceeds a critical value, a vortex-breakdown-induced central toroidal recirculation zone is estab...
