Investigating how streamwise riblets affect flow separation in low-reynolds-number compressor cascades, suggesting improvements in aerodynamics.

Flow separation decreased significantly with the application of streamwise riblets, enhancing performance.
Direct numerical simulation indicates a reduction in drag coefficient by 15% with riblet implementation.
Examining configurations across multiple riblet patterns in low-Reynolds-number environments strengthens conclusions surrounding efficiency.
Findings highlight the potential to optimize compressor designs through riblet use, though additional validation is needed.

Liu et al. (2026) studied this question.
