Numerical Prediction Of Turbulent Oscillating Flow In A Circular Pipe

Turbulence models are reviewed and discussed with respect to their applicability in oscillating flow modeling. The Larn-Brernhorst form of the low-Reynolds number k-/spl epsilon/ turbulence model is chosen for oscillating flow 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 very satisfactory. The instantaneous friction coefficients for fully developed flow are documented. The use of an effective Valensi number is proposed.
