Oscillating Flow About Tube Bundles.

Abstract

The lift, drag, and inertia coefficients have been determined experimentally for various tube bundles and for two cylinders at various relative positions subjected to harmonically oscillating flow. The force coefficients for the inline force have been analyzed through the use of the Morison's equation and the Fourier analysis. The transverse force or the lift force has been expressed in terms of its maximum value. The results have shown that the interference between the cylinders can give rise to complex flow patterns and to unexpectedly large force transfer coefficients. The results with two cylinder experiments have shed considerable light on the wake interference in harmonic flows. (Author)
