Jet vortex generators for turbulent flow separation control
Author(s): Selby, Gregory; Lin, J.; Howard, F.
Abstract: A parametric study was performed with jet vortex generators to determine their effectiveness in controlling flow separation associated with low speed turbulent flow over a two dimensional rearward-facing ramp. Results ...

Longitudinal grooves for bluff body drag reduction
Author(s): Quass, B.; Howard, F.; Weinstein, L.; Bushnell, D.
Abstract: Wind tunnel test results are presented for four axisymmetric bluff body configurations in order to determine their effect on form and pressure drag. It was found that drag reductions on the order of 40 are obtainable with an ...
