34 Re effect on CD

This video discusses how the coefficient of drag varies over a range of Reynolds numbers including the phenomena of creeping flow, oscillating Karmen vortexes, and compression of the turbulent wake. This is lecture 34 in the online Fluid Mechanics course CE 340 from Ohio University by Dr. Guy Riefler.

Nice video detailing each section of the Cd-Re graph! My lecturer doesn't even explain it well );

Thank you! Very useful.

Very useful thanks!

very useful

this is a long shot but i'll try anyway. It's still unclear to me why after the first separation (still laminar flow) the coefficent of drag dimishes. I would assume that because with incresing Re the separation point "moves counterclockwise" (if looking only at the upper half of the circle) the pressure gradient would become higher and higher thus increasing the drag coefficent

Very Useful but ..why are you speaking like dead....dont u have energy
