Extract

Experimental measurements of the separated flows around a range of tapered flat plates normal to a uniform stream are presented. Both the surface pressures and velocities in the wake are discussed. It turns out that even slight taper can modify the wake region of the flow significantly, and so produce a surprising degree of three-dimensionality into the overall flow structure. These experimental results point to the dangers in applying simple strip theories to highly separated flows.

Aerodynamic theory has evolved over the years to describe the flow fields around streamlined aircraft and their components, so as to provide, amongst other quantities, accurate estimates of the aerodynamic forces and moments.
