The experimental data of laser-Doppler anemometry (LDA) measurements inside an engine representative cavity rig are presented in this paper. Traverses using a two component LDA system have been carried out in the shaft bore and the cavity regions in order to map the axial and tangential velocity components. The velocity data are collected for a range of Rossby, Rotational, and Axial Reynolds numbers, Ro, Re?, and Rez, 0.08
