Abstract

Experiments were conducted in two curved rectangular ducts of different radii and the results compared with flow in a straight duct. The turbulent boundary layers developing on the curved walls were examined for mean flow properties. The law of the wall takes a modified form and the usual logarithmic portion applies over a very small range of the profiles on the inner walls and a slightly larger range on the outer walls. Similarity based on a defect law did not exist for any part of the flow examined.
