This paper presents a systematic slender-body theory for a slender particle
embedded in an arbitrary Stokes flow. Contrary to previous works, the body
is not necessarily of revolution. The approach consists of gaining the sur
face stress acting on the particle by asymptotically solving, with respect
to a slenderness ratio, a Fredholm boundary integral equation of the first
kind. The procedure approximates integrals depending upon a small parameter
by invoking a systematic formula. Special attention is paid to particles o
f elliptical dress-section and term-to-term comparisons are given for a sle
nder ellipsoid embedded in a rather simple Stokes flow.
