Experimental study of a three-dimensional pressure-driven turbulent boundary layer
- Virginia Polytechnic Inst. and State Univ., Blacksburg, VA (United States)
The characteristics of an incompressible 3-D turbulent boundary layer generated by a wing-body junction flow was studied experimentally. The data presented include time-mean static pressure and directly measured skin-friction magnitude on the wall. The mean velocity and all Reynolds stresses from a three-velocity-component fiber-optic laser-Doppler anemometer are presented at several stations along a line determined by the mean velocity vector component parallel to the wall in the layer where the u(sup 2) kinematic normal stress is maximum (normal stress coordinate system). The difference of the flow studied here lies in the fact that the mean flow variables depend on three spatial axes rather than two axes, such as flows in which the three-dimensionality of the flow has been generated either by a rotating cylinder or by a pressure gradient in one direction only throughout the flow.
