Fig. 5.41 Vortices above a delta wing: The symmetrical pair of vortices over a delta wing are made visible
by the use of dye in water flow. The wing is made of thin plate and has a semi-vertex angle of 15". The
angle of attack is 20" and the Reynolds number is 20000 based on chord. The flow direction is from top to
bottom. See also Fig. 5.40 on page 264. (The photograph was taken by H. Wer/e at ONERA, France.)
