FDS Wall Flows Part I: Straight Channels

Published

Author(s)

Randall J. McDermott

Abstract

We perform calculations of 2D laminar and 3D turbulent channel flow with periodic streamwise boundary conditions. From the laminar results we verify that the FDS wall boundary condition is second-order accurate. For the turbulent cases we adapt the wall stress model of Werner and Wengle to FDS and verify the implementation by replicating the Moody diagram, a plot of friction factor versus Reynolds number for turbulent pipe flow.
