Measurements in Fully Developed Turbulent Channel Flow

Measurements in a turbulent channel flow of air are presented for three Reynolds numbers. The design features of the present system suggest that the flow is a closer approximation to fully developed, two-dimensional turbulent flow between two parallel plates than those documented by previous investigators. Comparison of the new data with previous data reveal distinct differences, some of which can be attributed to differences in apparatus design. Interest in these data stems from the fact that channel flow serves as a reference flow for testing various theoretical models and experimental techniques involving turbulent shear flows.
