Eckert, E. R. G., Anderson, J. E., RuizUrbieta, M., Scott, C. J., Krall, K. M.
Experiments on pressure distribution and heat transfer on a grid simulating a parachute cloth were performed. The porosity of the grid was 25%. A pressurized wind-tunnel served as the flow facility....
Wind Tunnel Tests of a Trapped Vortex-High Lift Airfoil. (1998)
Two dimensional low speed wind-tunnel tests have demonstrated the feasibility of employing trapped vortex diffusion on a high lift airfoil configuration. All 11 percent supercritical airfoil was...
