THE USE OF DISKS TO APPROXIMATE FINITE AXISYMMETRICAL BODIES IN STOKES-FLOW

The analytically intractable problem of the Stokes flow past a finite cylinder is shown computationally to be well approximated by the use of an array of disks whose spacing must be sufficient to allow a formulation in terms of integral equations of the second kind. The translating cylinder within a pipe is similarly modeled and the method also allows the effects of simple streamlining or concavity to be quantified.
