Large-amplitude periodic pipe flow - A second-moment closure study
Abstract
A second-moment closure scheme is extended to incorporate the immediate near-wall region in large-amplitude periodic pipe flow, where turbulence Reynolds numbers are low. The model's development and testing for stationary flows is described. A detailed comparison is made between the present simulations and the 0.5 Hz experiment of Ramaprian and Tu (1981). The present model is shown to reproduce the behavior of equilibrium wall flows fairly well.
