Measurements in the axial flow over a cylinder-flare body of flare semi-angle 20 deg. the radius of longitudinal curvature of the transition piece between the cylinder and the conical flare being about 10 times the boundary layer thickness, are described. Analysis shows that the effects of this curvature die out so that the changes in second and third-order structural parameters found in the boundary layer on the flare can be attributed to lateral divergence. The destablizing effect of a given lateral strain rate is nearly the same as the effect of longitudinal curvature. (A)
