Abstract

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, Ahead of Print.
In the turbine rotor passage, hot streaks migrate radially toward the blade tip region, heating the tip surface and potentially causing localized high-temperature ablation. This issue is particularly pronounced in micro turbines due to the absence of ...
