The Forces Experienced by Two 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 one of two parallel elliptic cylinders in a uniform flow at small Reynolds numbers are calculated. When the thickness ratios of both elliptic cylinders are taken to be unity, the general expressions for these coefficients reduce to those for the case of two circular cylinders which have been obtained in the author’s previous paper. The expressions for the case of two flat plates are also included as a special case.
