An Experimental investigation into the drag performance of chevron-shaped protrusions in a turbulent channel flow: Experimental investigation into the drag and one dimensional velocity statistics

Contrary to conventional wisdom favouring smooth surfaces for drag reduction, the last decades have brought forth different textured surfaces showing drag reduction in turbulent boundary layers, of which riblets are the most studied.<br/>Sirovich and Karlson (1997) introduced a different textured surface named chevron-shaped protrusions,...
