Numerical prediction of turbulent oscillating flow in a circular pipe
Abstract
Turbulence models are reviewed and discussed with respect to their applicability in oscillatingflow modeling. The LamBremhorst form of the lowReynolds number kepsilon turbulence model is chosen for oscillatingflow modeling. Computations of oscillating flow in a finite pipe are compared with experimental data. While deficiencies of the turbulence model are identified, the overall agreement is shown to be satisfactory. The instantaneous friction coefficients for fully developed flow are documented. The use of an effective Valensi number is proposed.
