Abstract:

The flow in the cross-flow separation region of a 61 prolate spheroid at 10 deg angle of attack, ReL 4.20xl0exp 6, was investigated using a novel 3-D fiberoptic Laser Doppler Velocimeter 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.
