A butterfly uses an efficient and complex flight mechanism comprised of multiple interacting flow control devices that include flexible, micro-geometrically surface patterned, scaled wings. The following research ascertains if any aerodynamic advantages arise from the formation …
The objective of the present work was to investigate three dimensional unsteady vortex dominated flows using the spectral difference (SD) method and finite volume (FV) method. The simulations were carried out over a circular cylinder, a delta wing and a spiral-shaped wind turbin…
Secondary flows in turbomachinery and similar engineering applications are often dominated by a single streamwise vortex structure. Investigations into the control of these flows using periodic forcing have shown a discrete range of forcing frequency where the vortex is particul…
Influence of wing sweep on juncture flow has been investigated using three component laser Doppler velocimetry and body-surface pressure measurements. Configurations with forward and back sweep angles of 7.5°, 15°, 22.5°, 30° and 45° were studied. Comparisons were made with a ze…
