Abstract

Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, Volume 240, Issue 3, Page 373-385, May 2026.
The performance in the downstream swirling and upward swirling combustors with different swirler locations was evaluated. Unlike the axial recirculation formed by the interaction between swirling and direct flows in the downstream swirling combustor, ...
