Abstract

By relating the coefficients of some of the terms in the asymptotic expansion of the streamfunction to the force components and the torque on a body, together with the imposition of an integral constraint, enables the boundary element method to provide a closed system of equations for the steady slow flow generated by a rotlet in the presence of a circular cylinder. Excellent agreement is obtained between the numerical results and previous analytical expressions and some new results relating to forces and torques on the cylinder are presented.
