Numerical model and experimental research of a new two-tier micro-flame combustor for gas turbines

Abstract

The study of a novel two-tier micro-flame combustor for gas turbines involved comprehensive modelling using SolidWorks and ANSYS FLUENT software pack?ages, alongside physical experiments. Analysis of air-flow velocities, pressures, temperatures within the combustion chamber, and NOx emissions led to several key findings. The SolidWorks modelling confirmed stabilized air-flow and uniform pressure distribution, enhancing fuel combustion. Optimal air-flow velocities (15 m/s and 30 m/s) for different operating modes were determined, highlighting the importance of air-flow regulation. The ANSYS FLUENT analysis revealed efficient mixing of the fuel-air mixture through the device?s two tiers. The analysis of NOx emissions confirmed compliance with regulatory standards, up to 15 ppm. These results underscore the efficiency and stability of the combustor, making a signifi?cant contribution the advancement of gas turbines while meeting requirements for efficiency and environmental safety.
