... and rigidly supported cylinders in fixed positions. In the present paper the theory is extended to include the mean transverse force on the cylinders. Furthermore the calculation procedure is extended to include calculation of the static deflection of each riser in the array. Typical applications...

... ABSTRACT: This paper is a review of experimental research on vortex-induced transverse forces on smooth, rigid, fixed and elastically mounted circular cylinders, subjected to a variety of steady and periodic flows. The salient flow and geometric parameters influencing the vortex shedding...

... that interaction of the cylinder with its own wake is extremely important. Strong vortex shedding effects throughout all of the experiments were evident. Large transverse forces were observed at Reynolds numbers over 10 6 " The Morison equation proves to be a good model of the forces. Comparisons are made...

... Abstract This paper deals primarily with transversal forces at different elevations on a pile due to waves. Data are obtained from a model test setup with a 42 mm diameter pile in waves up to 0.70 m high. Some results of preliminary nature have been given. Introduction In-line wave forces...

... ABSTRACT The in-line and transverse forces acting on smooth and sand-roughened circular cylinders placed on a plane boundary (with no gap) in a sinusoidally oscillating flow in a U-shaped vertical water tunnel have been measured. The drag and inertia coefficients for the in-line force have...

... for the individual pipes in the riser by means of least square analysis. Further transverse forces and Strouhal numbers were analyzed. The results show that even with a distance greater than 3.5 diameters between the pipes in the outer ring and a relatively small central cylinder, a composite riser behaves largely...

... of neighbouring members has been measured in the form of interference coefficients. The results show reduction of drag on shielded cylinders but a significant increase (up to three times) of the maximum transverse force on a cylinder in the wake of another, the effects increasing with the flow orbit length...

..., and roughness effects on the in-line and transverse force coefficients (i.e., drag, inertia, and the lift coefficients have recently been carried out by Sarpkaya. These studies were prompted by the need for systematic data and partly by the controversy concerning the influence of Reynolds number and surface...

... ABSTRACT This paper presents the results of an extensive experimental investigation of the in-line and transverse forces acting on sand-roughened circular cylinders placed in oscillatory flow at Reynolds numbers up to 1,500,000; Keulegan-Carpenter numbers up to 100; and relative roughnesses...

... ABSTRACT The in-line and transverse forces acting on circular cylinders placed near a plane boundary in a sinusoidally oscillating fluid in a U-shaped vertical water tunnel have been measured. The drag and inertia coefficients for the in-line force have been determined through the use...
