Abstract

Periodic fully developed fluid flow characteristics are obtained numerically for three-dimensional turbulent flow in a corrugated duct. The method is based on the fully conserved control-volume representation of fully elliptic Navier-Stokes equations in a nonorthogonal body-fitted coordinate system. Turbulence is modeled via the two-equation (k-ε) model. The computations were performed for the ratio of the corrugation height to the interwall spacing ranging from 0.45 to 2.0, and for the corrugation angles of 30° and 45°, Experiments were also performed for pressure drop, velocity, and turbulence measurements, and for flow visualization.
