Experimental investigation of ridge-induced secondary motions in turbulent channel flows
Mattias Nilsson-Takeuchi, Bharathram Ganapathisubramani
Many engineering and environmental surfaces exhibit spatial heterogeneity in the spanwise direction and encompass multiple surface length scales. When the dominant spanwise length…

Effects of pressure gradient histories on skin friction and mean flow of high Reynolds number turbulent boundary layers over smooth and rough walls
Thomas Preskett, Marco Virgilio, Prateek Jaiswal +1
Experiments are conducted over smooth and rough walls to explore the influence of pressure gradient histories on skin friction and mean flow of turbulent boundary layers. Different…
