The response of a turbulent boundary layer to lateral divergence
Abstract
Measurements in the axial flow over a cylinderflare body of flare semiangle 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 thirdorder 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.
