The Forces experienced by a Lattice of Elliptic Cylinders in a Uniform Flow at Small Reynolds Numbers

Abstract

Using Imai's general method of solving two-dimensional Oseen's equations, the drag and lift coefficients for a lattice of parallel, equal and equidistant elliptic cylinders in a uniform flow at small Reynolds numbers are calculated. When the stagger is not present and the thickness ratio of the elliptic cylinders is taken to be unity, the expressions for these coefficients reduce to the case of a lattice of equal and equidistant circular cylinders which has been investigated by Tamada and Fujikawa.
