Abstract
A requirement for calculating an accurate velocity distribution in noncircular conduits is a knowledge of the secondary flow distribution in these conduits. The cause of these secondary flows is considered in this paper and a simple momentum transfer model for Reynolds stresses is used to effect a solution for the secondary flow in a square duct. The calculated secondary flows are similar in magnitude and direction to measurements reported in the literature.Keywords
