Summary: For comparison with the results of current experiments, a concise analytical method is developed to describe the non-axisymmetric flow generated by the edgewise sedimentation of a disk toward a plane wall. Since all Fourier modes contribute to the flow, the use of Abel transforms in earlier work [A. M. J. Davis, Phys. Fluids A 2, No. 3, 301-312 (1990; Zbl 0704.76018)] must be suitably extended in order to again obtain integral equations of the second kind. By expanding the wall effects in powers of \(D^{-1}\), where \(D\) is the distance from the disk axis to the wall, the dimensionless drag coefficient is found to order \(D^{-5}\) without having to solve the flow problem beyond the second Fourier mode.
