The paper presents the flow measurements within the leg portion of the horseshoe vortex at the blade and endwall junction. An uncambered blade of constant thickness downstream with a half-circular nose of an idealized blade was installed as an obstacle on a flat plate. The six components of the Reynolds stresses were measured in addition to the three mean velocity components at two cross-sectional planes by a triple-wire probe. The predominant vortical motion of the secondary flow occurs at the corner of the blade and endwall. The effect of the entrainment of the free-stream induced by the vortical motion of the Reynolds stress is found is <u^2>^^^- profiles near the blade, but not in <v^2>^^^- profiles. The diffusion of the Reynolds stresses is observed in a crossflow direction.
