要約

This paper describes recent experiments conducted at the University of New Brunswick in which uniformly sheared turbulence was subjected to plane mean flow curvature not coincident with the plane of the shear. One of the results was a swirling mean motion that caused the uniform shear to rotate about the tunnel centerline. In the first portion of the flow, the swirl was weak and the turbulence was subjected to plane curvature perpendicular to the plane of the shear. In the second portion, the swirl was well developed and the mean shear had been rotated by 30° towards the plane of the curvature. Measurements of all components of the mean velocity, Reynolds stress, and streamwise integral length scales are reported.
