Published Online: November 25, 2022
...Joshua M. Maynard; Andrew P. S. Wheeler; James V. Taylor; Roger Wells Direct numerical simulations (DNS) are performed of a cantilevered stator blade to identify the unsteady and turbulent flow structure within compressor tip flows. The simulations were performed with clearances of 1.6% and 3.2...
