Full three-dimensional measurements of the cross-flow separation region of a 6:1 prolate spheroid

The flow in the cross-flow separation region of a 1.37 m long, 6:1 prolate spheroid at 10 deg angle of attack was investigated with a novel 3D fiber-optic LDV. The probe was used to measure three simultaneous, orthogonal velocity components from within the model. The design and operation of this LDV...

Summary:The flow in the cross-flow separation region of a 1.37 m long, 6:1 prolate spheroid at 10 deg angle of attack was investigated with a novel 3D fiber-optic LDV. The probe was used to measure three simultaneous, orthogonal velocity components from within the model. The design and operation of this LDV probe is described, and velocity, Reynolds stress, and velocity triple-product measurements are presented from the inner boundary layer through the boundary-layer edge.
