..., Strouhal frequency, and the in-line force for cylinders with relative inclinations and spacings in a design-wave environment is an exceedingly complex problem. In the absence of data on the interaction between drag and inertia coefficients in wavy and harmonic flows for cylinder groups one is tempted...

... ABSTRACT The interference effect in steady and time-dependent flows is briefly reviewed and the drag and inertia coefficients for two particular riser configurations subjected to harmonic flow are presented. INTRODUCTION A body's resistance to flow is strongly affected by what surrounds...

... ABSTRACT An elastically-mounted cylinder may undergo hydroelastic transverse oscillations in harmonic flow when the reduced velocity, U r = U m /f n D, is about 5.5. At perfect synchronization, the Strouhal number remains constant throughout the cycle and the vortex-shedding frequency locks...

... ABSTRACT Transverse oscillations of a flexibly-mounted rigid cylinder in harmonic flow have been investigated through the use of a U-shaped vertical water tunnel. The results have shown that the largest amplitudes of oscillation for a given damping ratio, Keulegan-Carpenter number...

... obtained from tests in steady flow are not applicable to harmonic flows even when the fluid loading is predominantly drag. INTRODUCTI ON Of the scores of papers dealing with fluid loading on offshore structures none seems to have treated the effect of roughness on the force-transfer coefficients. Yet...
