Published in 2019 at "Chinese Journal of Aeronautics"

DOI: 10.1016/j.cja.2019.04.023

Abstract: The characteristics of turbulent boundary layer over streamwise aligned drag reducing riblet surface under zero-pressure gradient are investigated using particle image velocimetry. The formation and distribution of large-scale coherent structures and their effect on momentum… read more here.

Published in 2017 at "Experimental Thermal and Fluid Science"

DOI: 10.1016/j.expthermflusci.2017.03.006

Abstract: Abstract Measurement of three-dimensional (3D) turbulence over riblet surfaces is challenging due to the small size of the grooves and the requirement for measurement in the inner layer. The capability of two-dimensional (2D) and 3D… read more here.
