Effects of Step-Excrescence Location on Swept-Wing Transition Conference Paper uri icon

abstract

  • 2015 by Brian K. Crawford, Glen T. Duncan Jr., Matthew W. Tufts, William S. Saric, and Helen L. Reed. Two-dimensional step excrescences on a swept-wing model are studied in two low-disturbance environments, wind-tunnel and flight. The present study focuses at 1% chord. An extensive comparison is made with previous flight and wind-tunnel results at 15% chord using the same test article and same initial and boundary conditions. The combined sensitivity of curvature effects and streamwise location of the step excrescence is examined. Infrared thermography and hotwire anemometry results are presented and will be used to validate the companion computational effort by Tufts et al.
