- Title
Reynolds Stress Measurement Over Four Slender Delta Wings.
- Authors
Behfarshad, G.; Ahmed, N. A.
- Abstract
Flow over a delta wing separates along the edges of the wing, is three dimensional, turbulent and unsteady. An investigation into the characteristics of the flow over four low aspect ratio delta wings were examined. Data were taken at a chord Reynolds number of 6.35x105 at 30° angle of attack and at x/c=0.523 by hot-wire anemometer at different heights above the wings. The instantaneous longitudinal velocity signal was used to compute mean velocity and longitudinal Reynolds stress profiles. The velocity field inside the vortex core reaches a maximum of about twice the freestream velocity. Longitudinal Reynolds stress value decreases over the wings as the aspect ratio decreases.
