Abstract
Mean flow properties, including turbulent stresses, were fully measured in a turbulent Taylor vortex flow between stationary outer and rotating inner cylinders with a radius ratio of 1/0.92. The static pressure distribution on the outer wall confirmed that many turbulent Taylor vortex pairs about twice as high as the channel width continued to exist over a wide range of Taylor numbers varying by more than one digit. A new technique using a grid was effectively applied to fix a vortex pair to be measured at the required position during the velocity field measurements. In the core region extending over 60% of the channel width, the secondary flow contributed to the angular momentum transfer by about 90%. The turbulent stress distributions were characterized by production and convection due to the secondary flow.
