Abstract

Electrochemical measurements of the local wall shear were made along the inner bend of a curved pipe in the entry region, to examine the nature of the secondary-flow boundary-layer collision. Analysis by Stewartson, Cebeci & Chang (1980) predicts a vanishing of the wall shear at the collision point, but without flow reversal. The experimental results are in good agreement with the analytical predictions upstream of the collision point, and its location appears to be predicted accurately. However, downstream of the collision point agreement is poor.
