AN EXAMINATION OF FULLY DEVELOPED TURBULENT FLOW IN A SQUARE DUCT

Abstract

The problem of describing the velocity profiles and other flow data in a square duct was investigated using the boundary layer description due to Cornish. The existence of a negative local free stream velocity with components due to wake over the friction velocity function was discovered and a method of describing the profile as a function of its position within the pipe was deduced. A method was determined to predict total quantity flow in a square duct as a function of both centerline velocity and static pressure loss down the duct. Profiles were measured at a wide range of centerline velocities, and the theories were verified experimentally. (Author)
