Fig. 8. Mean velocity of fluid within the aesthetasc hair array as a function of
Reynolds number (calculated using aesthetasc diameter; L). The
natural flick occurs at a Re=2. Twenty velocity transects were
obtained at different locations within the aesthetasc array (as shown in
Fig. 7). Mean velocity was
computed as the area-averaged velocity along the mid-line of the 20 transects.
Error bars indicate one standard deviation.
