...Brian R. Elbing This study reexamines past studies of how drag-reducing polymer solutions modify the log-region of a developing turbulent boundary layer (TBL). The classical view was that the polymers modify the intercept constant without impacting the von Kármán coefficient, which results...

... ]. It is shown there that these calibrations, when applied to the remote microphone measurements, produce an accurate turbulent boundary layer pressure spectrum. The geometric angle of attack of the wing ( α g ) was changed by rotating the turn-table on which the wing was mounted. The junction...

... 12 2012 12 01 2014 Smooth and rough wall turbulent boundary layer profiles are frequently scaled using the wall shear velocity u*, thus it is important that u* is accurately known. This paper reviews and assesses several wall similarity techniques to determine u* and compares results...

... and favorable streamwise pressure gradients on entropy generation rates across turbulent boundary layers on flat plates and—secondarily—to assess a popular approximate technique for their evaluation. About two-thirds or more of the entropy generation occurs in the viscous part, known as the viscous layer...
