P. Freymuth,* F. Finaish,t and W. BankJ University of Colorado, Boulder, Colorado first frame shown is ^=47/64 s, the time between frame shown is At = 4/64 s for all sequences, and the frame height corresponds to an actual height of h= 16A cm. Smoke-generating liquid was released along the leading edge of the wing, marked by the left arrow on top of the first frame. The trailing edge is covered with smoke and its location is marked by the right arrow at top of the first frame. The tip location can be seen as a horizontal boundary of illumination
