Forces on cylinders and plates in an oscillating fluid

Abstract

The inertia and drag coeffi cien ts of cylinders and plates in simple sinusoidal c urrents are investigated. The midsection of a rectangu lar basin wi th standing wa ves s urging ill it is selected as t he locale of curren ts. The cyl inde rs and plates are fixed hori zontally a nd below t he water surface. The average values of the inertia and drag coefficients over a wave cycle show variations when the intensity of t he current and t he s ize of the cylinders or plates a re ch anged.
