Circulation Control by Slot Suction on a Circular Cylinder. Measured Force Characteristics of a Smooth Double-Slotted Cylinder.
Abstract
Force characteristics are presented for a uniformly smooth circular cylinder, equipped with one and two spanwise sharp-edged slots (slot separation 60 degrees, s/d = 0.05). Suction coefficients from zero to about 1.0 (per slot) were applied over the complete incidence range at low mainstream Mach number (Mn less than 0.15, Re = 100,000 to 700,000). The single-slot data are compared with earlier results for a relatively rough cylinder. The two-slot data are examined in some detail for two special cases, viz (1) zero suction rate over the complete incidence range, (2) full test range of suction coefficient at the particular incidence involving rear symmetry of slot position.
