Abstract
A rectangular cross section channel, designed and built by R. McKee to create the laminar secondary Taylor-Goertler vortex flow, was modified to expand the experimental investigation of the vortex flow. The modification allowed the hot wire anemometer, used to obtain velocity profiles, to be moved in both the radial and transverse direction. this additional freedom permitted a rectangular cross section of the flow to be investigated. It was concluded that the onset of Taylor-Goertler vortices was in agreement with existing information, that the intensity of the vortices increased with increasing flow rate, and turbulent fluctuations grew within the vortex structure. It was also concluded that flow is a curved channel resulted in distortion of the normally parabolic velocity profile shifting the maximum mean velocity toward the concave wall.
