The work reported in part 1 has been extended to cover flows past circular cylinders with wake splitter plates having 2 [less-than-or-eq, slant] L/D [less-than-or-eq, slant] 7 and to include flows past normal flat plates with splitter plates having L/D [less-than-or-eq, slant] 3·7. Pressure distributions and wake Strouhal numbers were measured and visualization studies carried out. The results obtained indicate that no further changes would be produced by lengthening the splitter plates beyond the limits tested.

The combined results of parts 1 and 2 provide coherent descriptions of the effects of wake splitter plates for all values of L/D of significance for the two profiles, which are representative of two distinct classes of bluff bodies, viz., those with cross-sections of curvilinear shape for which the flow separation points are not determined uniquely by the geometry and those for which the separation points are fixed.
