Turbulent shear flows over a concave surface are subjected to complicating influences by extra rates of strain like streamwise curvature. In addition to these effects, turbulent boundary layers become strongly three-dimensional in the mean flow because of the formation of the counter rotating longitudinal vortices. The objective of the present paper is to clarify experimentally the effects of streamwise concave curvature on the turbulent boundary layer flows without substantial pressure gradient. Much attention is paied to the flow behaviors in response to the introduction of curvature. Momentum thickness Reynolds number is 2 900 and the ratio of the boundary layer thickness to radius of curvature, δ/R, is 0.046 at the start of curvature.
